Get folder contents

Hi

How can I get the files in a folder - but only certain file types eg only txt file?

Thanks

Code:

---

DirectoryInfo dir = new DirectoryInfo("C:\\");
FileInfo[] f = dir.GetFiles("*.txt");
foreach(FileInfo t in f){
  Console.WriteLine(t.Name);
}

---

Edit:
I have to stop putting C# code in the VB.Net section

VB Code:

Dim dir As DirectoryInfo = New DirectoryInfo("C:\")
Dim f As FileInfo() = dir.GetFiles("*.txt")
For Each t As FileInfo In f
    Console.WriteLine(t.Name)
Next

I've got an odd problem. When I use:
dir.GetFiles("2003*.*")
one of my results is:
2011001XEAP_1_1.837
This also happens in a command line dir search. Any idea?

????

I created this file at home (using XP Pro), and dir does not return filenames that do not match. I'm using 2000 Pro at work. Is this a bug, or am I missing something simple?

hmm... I created two files.... "2011001XEAP_1_1.837" and "2003001XEAP_1_1.837"

only the latter came up in both.

are these the names including the extension?

I think it has something to do with the number of files in the directory. 837 is the file extension.
