System_CAPS_noteNote

The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.

The following example displays the header name/value pairs associated with this request.


                  // Create a new request to the mentioned URL.	
WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");		

// Assign the response object of 'WebRequest' to a 'WebResponse' variable.
WebResponse myWebResponse=myWebRequest.GetResponse();

// Release the resources of response object.
myWebResponse.Close();
Console.WriteLine("\nThe HttpHeaders are \n{0}",myWebRequest.Headers);
