WebRequest.Headers Property

When overridden in a descendant class, gets or sets the collection of header name/value pairs associated with the request.

Namespace:  System.Net
Assembly:  System (in System.dll)

public virtual WebHeaderCollection Headers { get; set; }

Property Value

Type: System.Net.WebHeaderCollection
A WebHeaderCollection containing the header name/value pairs associated with this request.

ExceptionCondition
NotImplementedException

Any attempt is made to get or set the property, when the property is not overridden in a descendant class.

The Headers property contains a WebHeaderCollection instance containing the header information to send to the Internet resource.

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);
