WebResponse^ myWebResponse = myWebRequest->GetResponse();

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


         // 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);


    ' Create a new request to the mentioned URL.	
    Dim myWebRequest As WebRequest = WebRequest.Create("http://www.contoso.com")
    
   ' Assign the response object of 'WebRequest' to a 'WebResponse' variable.
   
    Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
   ' Release the resources of response object.
   
 myWebResponse.Close()
Console.WriteLine(ControlChars.Cr + "The HttpHeaders are " + ControlChars.Cr + "{0}", myWebRequest.Headers)

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

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

Note

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.
