What is equivalent for "Response" method of ASP in VB.NET?

I am trying to implement oAuth authentication in my desktop application. In a code example I found over the internet is like below. I guess it is ASP.Net code but I'm using VB.Net for my project. 开发者_如何学CThe problem is I don't know what is equivalent for Request in VB.Net.

    If Request("oauth_token") Is Nothing Then
        MsgBox("Nothing")
    Else
        MsgBox("Something")
    End If

Both Request and Response are objects in VB as well as C#:

It's unclear which one you're referring to however; Response or Request?
