Creating and loading and Server.CreateObject("Microsoft.XMLDOM") in C#

Hello Everyone,

Can someone please help me figure out what is the equivalent C# code for the following:

set xmldoc = Server.CreateObject("Microsoft.XMLDOM")
xmldoc.load(Request)

I am trying to receive an xsl as dom object and I thought this might work

XslCompiledTransform xslDoc = (XslCompiledTransform)Server.CreateObject("MSXML2.DOMDocument.3.0");

but I am not sure how to load the Request.  I want to use this as part of an ASP.Net page.  

Thanks.
