.NET web form alternative to OpenFileDialogue

Hi all,
I'm trying to learn .NET while developing my application so I need help quickly ;-). (I was a Java/C++ developer). I want my users to be able to select multiple files for upload, such as in the Windows Forms OpenFileDialogue box. But there is nothing similar in the .NET framework (asp.net, c#.net) 2000 (we can't use 2005). I can use multiple file input boxes but this is visually nasty compared to the elegant point and click of VB. I realise you can't use a windows forms component as it needs to run on the server. Please tell me there is some pretty piece of code just waiting for me to plug it in!
Cheers,
Katie
