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

public virtual WebHeaderCollection Headers { get; }

Property Value

Type: System.Net.WebHeaderCollection
An instance of the WebHeaderCollection class that contains header values associated with this response.

ExceptionCondition
NotSupportedException

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

The Headers property contains the name-value header pairs returned in the response.

NoteNote:

The WebResponse class is an abstract class. The actual behavior of WebResponse instances at run time is determined by the descendant class returned by WebRequest.GetResponse. For more information about default values and exceptions, please see the documentation for the descendant classes, such as HttpWebResponse and FileWebResponse.

The following example displays all of the header name-value pairs returned in the WebResponse.

          // Create a 'WebRequest' object with the specified url. 	
         WebRequest myWebRequest = WebRequest.Create("http://www.contoso.com"); 

         // Send the 'WebRequest' and wait for response.
	  WebResponse myWebResponse = myWebRequest.GetResponse(); 

         // Display all the Headers present in the response received from the URl.
         Console.WriteLine("\nThe following headers were received in the response");

	  // Display each header and it's key , associated with the response object. 
         for(int i=0; i < myWebResponse.Headers.Count; ++i)  
		    Console.WriteLine("\nHeader Name:{0}, Header value :{1}",myWebResponse.Headers.Keys[i],myWebResponse.Headers[i]); 

         // Release resources of response object.
         myWebResponse.Close(); 
// Create a 'WebRequest' object with the specified url.
WebRequest* myWebRequest = WebRequest::Create(S"http://www.contoso.com");

// Send the 'WebRequest' and wait for response.
WebResponse* myWebResponse = myWebRequest->GetResponse();

// Display all the Headers present in the response received from the URl.
Console::WriteLine(S"\nThe following headers were received in the response");

// Display each header and its key , associated with the response object.
for (int i = 0 ; i < myWebResponse->Headers->Count ; ++i)
   Console::WriteLine(S"\nHeader Name: {0}, Header value : {1}",
   myWebResponse->Headers->Keys->Item[i], myWebResponse->Headers->Item[i]);

// Release resources of response object.
myWebResponse->Close();
