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

Public Overridable ReadOnly Property Headers As WebHeaderCollection

Property Value

Type: System.Net.WebHeaderCollection

An instance of the WebHeaderCollection class that contains header values associated with this response.

Exception Condition

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.


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 	
          Dim myWebRequest As WebRequest = WebRequest.Create("www.contoso.com")

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

          ' Display all the Headers present in the response received from the URl.
          Console.WriteLine(ControlChars.Cr + "The following headers were received in the response")

          ' Headers property is a 'WebHeaderCollection'. Use it's properties to traverse the collection and display each header
          Dim i As Integer

          While i < myWebResponse.Headers.Count
              Console.WriteLine(ControlChars.Cr + "Header Name:{0}, Header value :{1}", myWebResponse.Headers.Keys(i), myWebResponse.Headers(i))
i = i + 1
          End While

          ' Release resources of response object.
