Get a querystring key name

[.NET Developer]

Ok, this is probably simple but it's been driving me nuts.

If I have a URL like this: http://www.mysite.com/MyPage.aspx?MyKey

What code would I write to get that value "MyKey" out of the querystring?
Without the = and a value after it, is it considered a querystring value
still? I've tried Request.Params[0], Request.QueryString.Key[0], and nothing
is returning the value to me. I've driven down several levels into the
debugger and found the value (nested several object hierarchy levels deep)
but can't figure out how to get access to it.

Help?

Request.QueryString(0).Name

Nope...doesn't work (at least not in asp.net 1.1)

I found something that seems to work for now:

Request.Url.Query.Replace("?","");

Gets me what I need - just doesn't seem like the "right' way to get it.

Request.QueryString(0).Name

You can use GetKey for that. Here's some code. Let us know if it helps?

Try
' Make sure you pass everything such as
' ?mykey=4
Response.Write(Request.QueryString.GetKey(0))
Catch exc As Exception
Response.Write(exc.Message)
End Try

Well, you see, that's part of the problem I have to solve - I can't
guarantee the key will have "=[value]" after it. Which causes GetKey(0) to
fail.

Don't you think ?mykey should make GetKey(0) contain "mykey" ? Seems logical
to me. I don't think keys should be dependent on associated values.

if (this.Request.QueryString.AllKeys.Length == 1)

{

string keyName = this.Request.QueryString[0];

}
