//Try this
using System.IO

File.WriteAllLines("c:\TextFile.txt", arrUserandName)

That does not seem to work for an arraylist

I could not get it to work with streamwriter.  Do you have an example?

I tried this, but its not working either
  'Dim strTextFile As StreamWriter = New StreamWriter("c:\tsmemberstest.log")

        'For Each line In arrUserandName
            '    strTextFile.WriteLine(line)
        'Next
        'strTextFile.Close()
        'strTextFile.Dispose()

What version VB.Net are you using?...any particular reason for using an ArrayList?

Switch a List(Of String), then use s_chilkury's suggestion with List.ToArray().

Change:

    Dim arrUserandName As New ArrayList

To:

    Dim arrUserandName As New List(Of String)

Then you can use:

    File.WriteAllLines("c:\TextFile.txt", arrUserandName.ToArray)

what doesn't work?  is it an error message or failure to compile

have you imported System.IO?

are you using a web site (ASP.net), you may have no authority to "c:\tsmemberstest.log".  It is a problem I had, make some directory and grant all rights to everyone and try writing to there.




Dim strTextFile As  System.IO.StreamWriter = New  System.IO.StreamWriter("c:\tsmemberstest.log")

 For Each MyLine as string In arrUserandName
             strTextFile.WriteLine(MyLine )
Next

strTextFile.Dispose()
