C# ASP.NET: Detecting the Existence of URL Variable

[wbochar]

I've been useing URL variables with reasonable amount of success -- but I am unsure how to detect if a URL variable has been declared other than sifting through the header manually. In other lnaguages like Cold Fusion I could use somehting like:

isDefined("URL.ID")

I am using url variables for ID's on articles on a website so that they can be bookmarked. If the variable doesnt exist in the URL I want to take a default action. I am just trying to get out of a custom method and hoping for some simple solution that I have overlooked.

if (Page.Request.Params["id"] != null)
{
    // is set
}
else
{
    // is not set
}
