This question already has answers here:
Given a filesystem path, is there a shorter way to extract the filename without its extension?
(10 answers)
Closed 2 years ago.
How can I split the path to get the file name 1_Lighthouse_20140306143834816.jpg? And split the 1_Lighthouse_20140306143834816.jpg to get the 1 as for my reference that number 1 is already exist.
Use Path.GetFileName
if(countUser.Length > 0)
{
var file = Path.GetFileName(countUser[0]);
....
and then get the first character from the resulting string using the string indexer
char firstChar = file[0];
if(firstChar == '1')
.....
}
Use Path.GetFileName or Path.GetFileNameWithoutExtension to get the file name.
And string.Split to get the first part of the file name.
string filePath = "E:\\folder\1_Lighthouse_XXX.jpg";
var s = Path.GetFileNameWithoutExtension(filePath); //returns without the .jpg
var parts = s.Split(new[] { '_' });
var indexer = Convert.ToInt32(parts[0]);
for (int i = 0; i < files.Count; i++)
{
//string path = AppDomain.CurrentDomain.BaseDirectory + "Uploads/";
//string filename = Path.GetFileName(Request.Files[i].FileName);
HttpPostedFileBase file = files[i];
//string fname;
// Checking for Internet Explorer
if (Request.Browser.Browser.ToUpper() == "IE" || Request.Browser.Browser.ToUpper() == "INTERNETEXPLORER")
{
string[] testfiles = file.FileName.Split(new char[] { '\\' });
fname = testfiles[testfiles.Length - 1];
}
else
{
fname = file.FileName;
}
}

I have an entry and label I want to format my text to my label like this:
"email#gmail.com", "email2#gmail.com", "email3#gmail.com"
this is what I enter in my entry field:
email#gmail.com /space/ email2#gmail.com /space/ email3#gmail.com or
email#gmail.com,email2#gmail.com,email3#gmail.com
The separator is a space or comma. How can I format my output to the one above?
Good question!
string entry = Entry.Text;
List<string> arrayfromEntry = new List<string>();
if (entry.Contains(" ") == true){
arrayfromEntry = entry.Split(new char[] { ' ' }).ToList();
}
else{
arrayfromEntry = entry.Split(new char[] { ',' }).ToList();
}
for (int i = 0; i < arrayfromEntry.Count(); i++){
arrayfromEntry[i] = '"' + arrayfromEntry[i] + '"';
}
string f = (string.Join(", ",arrayfromEntry));
f = f.Remove(f.Count()-2,2);
f = f+'"';
textToLabel = f;
Where Entry.Text is the text from your entry and textToLabel changes the text of your label, this should work.
Based on the #jamesfdearborn answer, but using StringBuilder instead
string entry == "aaaa#ttttt.com,bbbb#ttttttyyy.com,tttt#errrer.com,yyyyyy#rrrttr.com,uuuuu#yuyuy.com";
var inputSeparator = ','; //comma is the separator in this case you can change it
var outputSeparator = ',';
var arrayfromEntry = entry.Split(inputSeparator).ToList();
var sb = new StringBuilder();
for (int i = 0; i < arrayfromEntry.Count(); i++)
{
sb.AppendFormat("\"{0}\"{1}",arrayfromEntry[i],outputSeparator);
}
sb.Remove(sb.ToString().Count()-1, 1);
sb.ToString() //result here
//output
//"aaaa#ttttt.com","bbbb#ttttttyyy.com","tttt#errrer.com","yyyyyy#rrrttr.com","uuuuu#yuyuy.com"
you can change the output or the the input separator
This InDesign Javascript iterates over textStyleRanges and converts text with a few specific appliedFont's and later assigns a new appliedFont:-
var textStyleRanges = [];
for (var j = app.activeDocument.stories.length-1; j >= 0 ; j--)
for (var k = app.activeDocument.stories.item(j).textStyleRanges.length-1; k >= 0; k--)
textStyleRanges.push(app.activeDocument.stories.item(j).textStyleRanges.item(k));
for (var i = textStyleRanges.length-1; i >= 0; i--) {
var myText = textStyleRanges[i];
var converted = C2Unic(myText.contents, myText.appliedFont.fontFamily);
if (myText.contents != converted)
myText.contents = converted;
if (myText.appliedFont.fontFamily == 'Chanakya'
|| myText.appliedFont.fontFamily == 'DevLys 010'
|| myText.appliedFont.fontFamily == 'Walkman-Chanakya-905') {
myText.appliedFont = app.fonts.item("Utsaah");
myText.composer="Adobe World-Ready Paragraph Composer";
}
}
But there are always some ranges where this doesn't happen. I tried iterating in the forward direction OR in the backward direction OR putting the elements in an array before conversion OR updating the appliedFont in the same iteration OR updating it a different one. Some ranges are still not converted completely.
I am doing this to convert the Devanagari text encoded in glyph based non-Unicode encoding to Unicode. Some of this involves repositioning vowel signs etc and changing the code to work with find/replace mechanism may be possible but is a lot of rework.
What is happening?

This is untested since I'm not able to test against your document, but try using getElements() like below:
var doc = app.activeDocument;
var stories = doc.stories;
var textStyleRanges = stories.everyItem().textStyleRanges.everyItem().getElements();
for (var i = textStyleRanges.length-1; i >= 0; i--) {
var myText = textStyleRanges[i];
var converted = C2Unic(myText.contents, myText.appliedFont.fontFamily);
if (myText.contents != converted)
myText.contents = converted;
if (myText.appliedFont.fontFamily == 'Chanakya'
|| myText.appliedFont.fontFamily == 'DevLys 010'
|| myText.appliedFont.fontFamily == 'Walkman-Chanakya-905') {
myText.appliedFont = app.fonts.item("Utsaah");
myText.composer="Adobe World-Ready Paragraph Composer";
}
}
A valid approach is to use hyperlink text sources as they stick to the genuine text object. Then you can edit those source texts even if they were actually moved elsewhere in the flow.
//Main routine
var main = function() {
//VARS
var doc = app.properties.activeDocument,
fgp = app.findGrepPreferences.properties,
cgp = app.changeGrepPreferences.properties,
fcgo = app.findChangeGrepOptions.properties,
text, str,
found = [], srcs = [], n = 0;
//Exit if no documents
if ( !doc ) return;
app.findChangeGrepOptions = app.findGrepPreferences = app.changeGrepPreferences = null;
//Settings props
app.findChangeGrepOptions.properties = {
includeHiddenLayers:true,
includeLockedLayersForFind:true,
includeLockedStoriesForFind:true,
includeMasterPages:true,
}
app.findGrepPreferences.properties = {
findWhat:"\\w",
}
//Finding text instances
found = doc.findGrep();
n = found.length;
//Looping through instances and adding hyperlink text sources
//That's all we do at this stage
while ( n-- ) {
srcs.push ( doc.hyperlinkTextSources.add(found[n] ) );
}
//Then we edit the stored hyperlinks text sources 's texts objects contents
n = srcs.length;
while ( n-- ) {
text = srcs[n].sourceText;
str = text.contents;
text.contents = str+str+str+str;
}
//Eventually we remove the added hyperlinks text sources
n = srcs.length;
while ( n-- ) srcs[n].remove();
//And reset initial properties
app.findGrepPreferences.properties = fgp;
app.changeGrepPreferences.properties = cgp;
app.findChangeGrepOptions.properties =fcgo;
}
//Running script in a easily cancelable mode
var u;
app.doScript ( "main()",u,u,UndoModes.ENTIRE_SCRIPT, "The Script" );
EDIT - Revised the title of my post to make it more relevant to the problem.
I have folders that may or may not contain subfolders that start with "REV". If there are subfolders that start with "REV" they are followed by an integer value padded with leading zeros. (ie: REV010 or REV003).
My goal here is to:
find the test folder (C:\temp\TEST\REV003)
Read the string name of the folder and parse its integer value
Add the integer to a list of integers. Find the max integer value
Increment the max integer value
Create a new string folder name starting with "REV" and padded with new int value
When I debug the code (below), it cannot seem to find the REV003 folder (The folder definitely exists in the path).
Is something wrong with my LINQ statement in finding the folder?
Also, if there is an easier procedure to achieve the same thing - I'm definitely open for it! Thanks!
int nextRev = 0;
List<int> listOfRevs = new List<int>();
IEnumerable<string> revFolders = Directory.GetDirectories(destDirName, "*REV*", SearchOption.AllDirectories).Where(f => f.StartsWith("REV"));
foreach (var rev in revFolders)
{
Console.WriteLine(int.Parse(rev.Replace("REV", "")));
listOfRevs.Add(int.Parse(rev.Replace("REV", "")));
}
if (listOfRevs.Count > 0)
{
nextRev = listOfRevs.Max();
Console.WriteLine(nextRev);
nextRev++;
}
revFolder = "REV" + nextRev.ToString("000");
Console.WriteLine("New Folder: " + revFolder);
** UPDATE **
Thanks to NetMage the problem was fixed, however I still had a few bugs. Here's the working code:
string revf = "";
int nextRev = 0;
List<int> listOfRevs = new List<int>();
IEnumerable<string> revFolders = Directory.GetDirectories(destDirName, "REV*", SearchOption.AllDirectories);
foreach (var rev in revFolders)
{
if (rev.Contains("REV"))
{
revf = rev.Split('\\').Last();
listOfRevs.Add(int.Parse(revf.Replace("REV", "")));
}
}
if (listOfRevs.Count > 0)
{
nextRev = listOfRevs.Max();
nextRev++;
}
revFolder = "REV" + nextRev.ToString("000");
Change your directory search to
IEnumerable<string> revFolders = Directory.GetDirectories(destDirName, "REV*", SearchOption.AllDirectories);
Based on the results from this, you will to change the maximum finding code - I would use LINQ:
var maxREV = Directory.GetDirectories(destDirName, $"REV*", SearchOption.AllDirectories)
.Select(d => Int32.TryParse(Path.GetFileName(d).Substring(3), out int num) ? num : (int?)null)
.Where(n => n.HasValue)
.Select(n => n.Value)
.Max();
var revFolder = "REV" + (maxREV+1).ToString("000");
Console.WriteLine("New Folder: " + revFolder);
I put in some error handling to skip files that don't have an integer after "REV".
I have a text file that contains 50 student names and scores for each student in the format.
foreName.Surname:Mark
I have figured out how to split up each line into a forename, surname and mark using this code.
string[] Lines = File.ReadAllLines(#"StudentExamMarks.txt");
int i = 0;
var items = from line in Lines
where i++ != 0
let words = line.Split(' ', '.', ':')
select new
{
foreName = words[0],
Surname = words[1],
Mark = words[2]
};
I am unsure of how i would incorporate a findMax algorithm into to find the highest mark and display the pupil with the highest mark. this as i have not used text files that often.
You can use any sorting algorithm there is a Pseudo Code available to find maximum number in any list or array..
Try this code, required just parse all files.
string[] lines = File.ReadAllLines(#"StudentExamMarks.txt");
string maxForeName = null;
string maxSurName = null;
var maxMark = 0;
for (int i = 0; i < lines.Length; i++)
{
var tmp = lines[i].Split(new char[] { ' ', '.', ':' }, StringSplitOptions.RemoveEmptyEntries);
if (tmp.Length == 3)
{
int value = int.Parse(tmp[2]);
if (i == 0 || value > maxMark)
{
maxMark = value;
maxForeName = tmp[0];
maxSurName = tmp[1];
}
}
}
I have about 2200 different files in a few different folders, and I need to rename about about 1/3 of them which are in their own subfolder. Those 700 are also in various folders as well.
For example, there might be
The top-most folder is Employees, which has a few files in it, then the folder 2002 has a few, 2003 has more files, 2004 etc.
I just need to attach the word "Agreement" before the existing name of each file. So instead of it just being "Joe Schmoe.doc" It would be "Agreement Joe Schmoe.doc" instead.
I've tried googling such scripts, and I can find stuff similar to what I want but it all looks completely foreign to me so I can't understand how I'd modify it to suit my needs.
Oh, and this is for windows server '03.
I need about 2 minutes to write such script for *NIX systems (may be less), but for Windows it is a long song ... ))
I've write simple VBS script for WSH, try it (save to {script-name}.vbs, change Path value (on the first line of the script) and execute). I recommend to test script on small amount of data for the first time just to be sure if it works correctly.
Path = "C:\Users\rootDirectory"
Set FSO = CreateObject("Scripting.FileSystemObject")
Sub visitFolder(folderVar)
For Each fileToRename In folderVar.Files
fileToRename.Name = "Agreement " & fileToRename.Name
Next
For Each folderToVisit In folderVar.SubFolders
visitFolder(folderToVisit)
Next
End Sub
If FSO.FolderExists(Path) Then
visitFolder(FSO.getFolder(Path))
End If
I used to do bulk renaming with batch scripts under Windows. I know it's a snap on *nix (find . -maxdepth N -type f -name "$pattern" | sed -e 'p' -e "s/$str1/$str2/g" | xargs -n2 mv). Buf after some struggle in vain, I found out, to achieve that effect using batch scripts is almost impossible. So I turned to javascript.
With this script, you can add prefix to file names by 'rename.js "s/^/Agreement /" -r *.doc'. A caret(^) means to match the beginning. The '-r' options means 'recursively', i.e. including sub-folders. You can specify a max depth with the '-d N' option. If neither '-r' or '-d N' is given, the script does not recurse.
If you know the *nix 'find' utility, you would notice that 'find' will match the full path (not just the file name part) to specified regular expression. This behavior can be achieved by supplying the '-f' option. By default, this script will match the file name part with the given regular expression.
If you are familiar with regular expressions, complicated renaming is possible. For example, 'rename.js "s/(\d+)/[$1]/" *' which uses grouping to add brackets to number sequences in filenames.
