WebRequest.Credentials Property

When overridden in a descendant class, gets or sets the network credentials used for authenticating the request with the Internet resource.

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

public virtual ICredentials Credentials { get; set; }
/** @property */
public ICredentials get_Credentials ()

/** @property */
public void set_Credentials (ICredentials value)

public function get Credentials () : ICredentials

public function set Credentials (value : ICredentials)

Not applicable.

Property Value

An ICredentials containing the authentication credentials associated with the request. The default is a null reference (Nothing in Visual Basic).

Exception typeCondition

NotImplementedException

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

The Credentials property contains the authentication credentials required to access 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 sets the Credentials property using the default credentials of the current user. When the request is made, credentials stored in this property are used to validate the client. This is identical to setting the UseDefaultCredentials property to true.

// Create a request for the URL.         
WebRequest request = WebRequest.Create ("http://www.contoso.com/default.html");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
