The QueryString collection is used to retrieve the variable values in the HTTP query string.

The HTTP query string is specified by the values following the question mark (?), like this:

Link with a query string

The line above generates a variable named txt with the value "this is a query string test".

Query strings are also generated by form submission, or by a user typing a query into the address bar of the browser.

And see this sample : http://www.codeproject.com/Articles/5876/Passing-variables-between-pages-using-QueryString

The HttpRequest class represents the request made to the server and has various properties associated with it  such as QueryString   The ASP NET run-time parses a request to the server and populates this information for you   Read HttpRequest Properties for a list of all the potential properties that get populated on you behalf by ASP NET    Note  not all properties will be populated  for instance if your request has no query string  then the QueryString will be null empty  So you should check to see if what you expect to be in the query string is actually there before using it like this   if   String IsNullOrEmpty Request QueryString  pID              Query string value is there so now use it     int thePID   Convert ToInt32 Request QueryString  pID
