What's the best thing to use in VB 2005 to replace the file system object I used in VB6?

 I can't seem to get any reference to System.IO.Filesystem working ("Visual Basic 2005" page 983) and my.computer.filesystem doesn't seem to define the file object for example.

Sorry about that. Page 983 is misleading. FileSystem doesn't seem to be in System.IO, it's My.Computer.FileSystem. In real life, it's defined in the Microsoft.VisualBasic.FileIO namespace. I need to fix that appendix.

The System.IO.File class provides Shared methods for working with files: AppendText, Create, Copy, Exists, Delete, etc. See page 986.

My guess is that you want the FileInfo class (page 991). A FileInfo object represents a file and has methods for working with it. For example, you create the object like this:

    Dim file_info As New FileInfo("C:\test.txt")

Then you can use its methods:

    If file_info.Exists() Then ...

If that's not what you mean, let me know what you want to do with the file and I'll see if I can find the appropriate class.

Thanks Rod...

I'm missing something basic :] here! I'm struggling with my first VB6-to-.net project and I cant find any way to reference FileInfo.

If I type (as you suggest),
  Dim file_info As New FileInfo("C:\test.txt")
I get an error - Type 'FileInfo' is not defined.

I'm obviously missing something about namespaces or framework classes. What do I need to do?

You need to tell VB what namespace to look in for the class. You can either provide the full namespace in the object like this:

    Dim file_info As New System.IO.FileInfo("C:\test.txt")

Or you can use an Imports statement. At the *very* top of the file before anything else, put:

    Imports System.IO

That tells VB to look in the System.IO namespace for objects. Now you can use this:

    Dim file_info As New FileInfo("C:\test.txt")
