A web application of course wouldn't have any of the standard OS controls. It's a web application, not a fat client application. The only reason to ever present the user with a "File" dialog box is so they can upload a file. The standard HTML "file input" form element has been around for ages for just that reason.
ASP.NET is bound to have a much more complicated, hard to understand, and pointlessly obscure version of the control.
Ah, here it is: System.Web.UI.HtmlControls.HtmlInputFile.
Simple web searchs for that or for "ASP.NET File Upload" should get you the rest of what you need to know.
