How do you test your Request.QueryString[] variables?

Question

I frequently make use of Request.QueryString[] variables.

In my Page_load I often do things like:

       int id = -1;

             


        

Answer 1

I'm using a little helper method:

public static int QueryString(string paramName, int defaultValue)
{
    int value;
    if (!int.TryParse(Request.QueryString[paramName], out value))
        return defaultValue;
    return value;
}

This method allows me to read values from the query string in the following way:

int id = QueryString("id", 0);
