When you are processing an HTTP request in ASP.NET you can retrieve the user-provided query string parameters using the HttpRequest.QueryString property.  This property is an instance of the NameValueCollection class.

If the user has provided multiple parameters with the same key in the query string, HttpRequest.QueryString[key] will return all the values concatenated together with commas.  If you would rather process the values individually, use HttpRequest.QueryString.GetValues(key), which will return an array of all the provided values.

For example:

URL: http://example.com?a=1&a=2
HttpRequest.QueryString["a"] = "1,2"
HttpRequest.QueryString.GetValues("a") = { "1", "2" }

I spent many weeks of my childhood, along with a substantial portion of last weekend, playing Might and Magic 2, which I purchased in a bundle from GOG.com.

Fond memories.
