Headers Property

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 Overridable Property Headers As WebHeaderCollection
Dim instance As WebRequest
Dim value As WebHeaderCollection

value = instance.Headers

instance.Headers = value
/** @property */
public WebHeaderCollection get_Headers ()

/** @property */
public void set_Headers (WebHeaderCollection value)

public function get Headers () : WebHeaderCollection

public function set Headers (value : WebHeaderCollection)

Property Value

A WebHeaderCollection containing the header name/value pairs associated with this request.

Exception typeCondition


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.


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 System.Net.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.    
    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.
Console.WriteLine(ControlChars.Cr + "The HttpHeaders are " + ControlChars.Cr + "{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.
Console.WriteLine("\nThe HttpHeaders are \n{0}", myWebRequest.
