multi lining files in IsolatedStorage # Windows Phone 7 - windows-phone-7

Question

i have created some files in the IO
in the "car" files, i would like to put some other reference like model, color etc...
so my question is : is it possible to have a multi-lining files in the IO
if yes how can i get them in the streamreader
// i want to storage many parameters in a file and find them again with the streamreader
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
//reception des parametres de la listbox
base.OnNavigatedTo(e);
string parameter = this.NavigationContext.QueryString["parameter"];
this.tbTitre.Text = parameter;
try
{
//Create a new StreamReader
StreamReader editionDevisReader = null;
IsolatedStorageFile probyOrange = IsolatedStorageFile.GetUserStoreForApplication();
//Read the file from the specified location.
editionDevisReader = new StreamReader(new IsolatedStorageFileStream("devis\\"+parameter+".txt", FileMode.Open, probyOrange));
//Read the contents of the file .
string textFile = editionDevisReader.ReadLine();
//Write the contents of the file to the TextBlock on the page.
tbTitre.Text = textFile;
while (editionDevisReader != null)
{
RowDefinition rowdefinition = new RowDefinition();
TextBlock textblock = new TextBlock();
textblock.HorizontalAlignment = new System.Drawing.Size(48, 20);
}
editionDevisReader.Close();
}
catch
{
//If the file hasn't been created yet.
tbTitre.Text = "veuillez d abord creer le fichier";
}
thx a lot all

Answer 1

Yes, you can save anything (up to a point) in a file:
using (var store = IsolatedStorageFile.GetUserStoreForApplication())
{
using (var isfs = new IsolatedStorageFileStream("myfile.txt", FileMode.OpenOrCreate, store))
{
using (var sw = new StreamWriter(isfs))
{
sw.Write("anything really. Here it's just a string but could be a serialized object, etc.");
sw.Close();
}
}
}
You can then read the file with:
var result = string.Empty;
try
{
using (var store = IsolatedStorageFile.GetUserStoreForApplication())
{
if (!store.FileExists("myfile.txt"))
{
return result;
}
using (var isfs = new IsolatedStorageFileStream("myfile.txt", FileMode.Open, store))
{
using (var sr = new StreamReader(isfs))
{
string lineOfData;
while ((lineOfData = sr.ReadLine()) != null)
{
result += lineOfData;
}
}
}
}
}
catch (IsolatedStorageException)
{
result = string.Empty; // may have partial data/file before error
}
return result;

You can use
StreamReader.Writeline
and
StreamRead.ReadLine
to write and read blocks of text seperated by line feeds.
