File.Create - ArgumentExcepti on was unhandled - illegal characters in path

I am having problems using the file.create method within a function
that is called when looping through an array of filepaths.

If I call my function with a hardcoded file path --C:\Temp.txt the
function creates the file as expected.

When I loop through my array I get the error - "ArgumentExcept ion was
unhandled - Illegal characters in path"

The value "C:\Temp.tx t" is the first value in the array - as it works
when hard coded and not when passed from the array I presume there is
something else I am missing.

Could this be related to character encoding?

TIA

I suggest to post the code calling 'File.Create' and maybe the code used to
fill the array.

No probs - It relates to an FTP class (included below my code) - it
works when I download a single file, or if I hard code a file name
into the destination path -

Sub FTP_DownloadFol derContents(ByV al ftpFolder As String, ByVal
sDestinationPat h As String, ByVal sMask As String)
Dim sSourceFiles As String()
Dim sDestFiles As String()
Dim objFTP As New clsFTP
Dim strSite As String
Dim strSiteDir As String
Dim strUID As String, strPwd As String

strSite = My.Settings.ftp _Server
strSiteDir = My.Settings.ftp _SOURCE_Folder
strUID = My.Settings.ftp _User
strPwd = My.Settings.ftp _Password
objFTP.RemoteHo st = strSite
objFTP.RemotePa th = strSiteDir
'slashes are optional at beginning and end of RemotePath!
objFTP.RemoteUs er = strUID
objFTP.RemotePa ssword = strPwd
objFTP.RemotePo rt = 21

'Ensure FTP folder is formatted correctly
ftpFolder = FtpFolderName(f tpFolder)

'Change to the required FTP folder
objFTP.ChangeDi rectory(ftpFold er)

If objFTP.Login() = True Then
objFTP.SetBinar yMode(True)
'UPLOAD FILE
'objFTP.UploadF ile(strFullPath , False)
'GET FILE LIST
sSourceFiles = objFTP.GetFileL ist(sMask)
sDestFiles = objFTP.GetFileL ist(sMask)
objFTP.CloseCon nection()
objFTP = Nothing

'DESTINATION SETTINGS

'LOOP THROUGH FILE LIST AND DOWNLOAD EACH FILE
Dim sTempSourceFile As String = "Test_1.txt "
Dim sTempDestFile As String = "Test_1.txt "
Dim i As Long
For i = 0 To sSourceFiles.Ge tUpperBound(0)
If Len(sSourceFile s(i)) Then
FTP_DownloadFil e(sSourceFiles( i), ftpFolder,
sDestinationPat h & "\" & sSourceFiles(i) )
End If
Next i

End If
End Sub

--------------------------------- CLASS CONTAINED BELOW THIS POINT
----------------------------------
'----------------------------------------------------------------
' Class : clsFTP.vb
' Description : This class will enable a developer to
' perform FTP Processing in VB.NET.
' The class supports such features as:
' - Uploading a file.
' - Create/Remove a directory.
' - Remove a file.
' - and much much more...
' Date : 7th February 2002.
' Conversion : The code was converted from C# code.
' Note : If this code works it was converted by
' Vick S. If it doesn't it was converted
' by someone else. :-)
' Also note that the code DOES NOT
' ACCOMODATE for proxy servers. Only
' DIRECT connections to FTP Sites.
'
' Bit Shifting within VB.NET 2002 is not supported via the
' traditional bit shifting operators (i.e. << - Bitwise left
' and >- Bitwise right).
' Dividing a number by 2^16 in VB.NET 2002 is the same as bit-
' shifting right 16 positions.
' Multiplying a number by 2^16 in VB.NET 2002 is the same as
' bit-shifting left 16 positions.
'
' Check out the following MSDN Article on bitshifting in
' VB.NET 2003:
' - Visual Basic .NET 2003 Language Changes
' - By Duncan Mackenzie.

Sub FTP_DownloadFol derContents(ByV al ftpFolder As String, ByVal
sDestinationPat h As String, ByVal sMask As String)
[...]
FTP_DownloadFil e(sSourceFiles( i), ftpFolder,
sDestinationPat h & "\" & sSourceFiles(i) )
Just a little note: I suggest to use 'System.IO.Path .Combine' instead of
'... & "\" & ...' to concatenate path components. Your code will fail if
'sDestinationPa th' is "C:\".
