Remarks

Note:

This method returns a new instance of a class that derived from System.Net.WebRequest . The Type of this new instance is determined at run time by the scheme of the URI in requestUriString. For example, when a URI beginning with http:// is passed in requestUriString, a System.Net.HttpWebRequest instance is returned.

Classes that derive from System.Net.WebRequest that are created to handle other requests are registered with the WebRequest.RegisterPrefix(string, IWebRequestCreate) method.
