Getting the Current URL in Asp.Net

We had the need within a custom asp.Net control this week to obtain the current URL, compare it to a value, and take action if the values matched. I found online some quick and easy code to determine the URL of the page the control is loading on and the function to take action was developed rather quickly thereafter.

Here is the basic code to get the URL:

Request.Url.ToString()

And using a combination of the Mid function and the Instr function, we are able to match values regardless of the environment the code is running in:

If Mid(strLinkURL, InStr(strLinkURL, "Pages")) = Mid(Request.Url.ToString(), 

InStr(Request.Url.ToString(), "Pages")) Then

       strReturn = "" & strLinkText & ""

Else

       strReturn = "" 
& strLinkText & ""

End If
