System Error. Code: 123.
The filename, directory name, or volume label syntax is incorrect
Error:
not able transfer file due to file not exists. I have inputted correct
Tools:
Using superb old version of .NET
Using superb old version of window server
Expected result:
able transfer multiple files in "D:\dq*.csv" and the file modified date must be today's date

Answer 1

I have inputted correct
Nope, you haven't. From the WinSCP documentation for the localPath argument:
Full path to local file or directory to upload. Filename in the path can be replaced with Windows wildcard1 to select multiple files. To upload all files in a directory, use mask *.
That is, it expects one path, not multiple.
Given your requirement for filtering on LastWriteTime, passing "D:\dq\*.csv" as the argument is not a viable option, so the solution is to upload the files one-by-one:
# ...
try{
# Connect
$session.Open($sessionOptions)
#File list:
Write-Host ("File list: ")
#transferoptions
$transferOptions = New-Object WinSCP.TransferOptions
#$transferOptions.FileMask = "*.*"
$transferOptions.FilePermissions = $Null # This is default
$transferOptions.PreserveTimestamp = $False # if Timestamp on file is enable
# Loop through each relevant file
foreach($localFile in Get-ChildItem "D:\dq\*.csv" | Where-Object {($_.LastWriteTime -ge [datetime]::today)}){
$remotePath = "/Outbox/"
# Upload files, collect results
$transferResult = $session.PutFileToDirectory($localFile.FullName, $remotePath, $false, $transferOptions)
# Success or error?
if ($transferResult.Error -eq $Null) {
#$transferResult = $session.PutFiles($localPath, $remotePath, $False, $transferOptions).Check()
Write-Host ("Upload of {0} succeeded, moving to save" -f $transferResult.FileName)
}
else {
Write-Host ("Upload of {0} failed: {1}" -f $transferResult.FileName, $transferResult.Error.Message)
}
}
}
finally{
# ...
}

Answer 2

The answer by #Martias is correct. You cannot pass multiple paths to Session.PutFiles.
But you can let WinSCP itself pick the today's *.csv files with just two lines of code, using todays constraint.
Using Session.PutFilesToDirectory would also make the code somewhat simpler.
$transferOptions = New-Object WinSCP.TransferOptions
# (your other transfer options)
$transferOptions.FileMask = ">=today"
$transferResult =
$session.PutFilesToDirectory(
$localPath, $remotePath, "*.csv", $False, $transferOptions).Check()
