ICredentials.GetCredential Method

Returns a NetworkCredential object that is associated with the specified URI, and authentication type.

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

NetworkCredential^ GetCredential (
	Uri^ uri, 
	String^ authType
)
NetworkCredential GetCredential (
	Uri uri, 
	String authType
)
function GetCredential (
	uri : Uri, 
	authType : String
) : NetworkCredential
Not applicable.

Parameters

uri

The Uri that the client is providing authentication for.

authType

The type of authentication, as defined in the IAuthenticationModule.AuthenticationType property.

Return Value

The NetworkCredential that is associated with the specified URI and authentication type, or, if no credentials are available, a null reference (Nothing in Visual Basic).

The GetCredential method returns a NetworkCredential instance that contains the credentials that are associated with the specified URI and authorization scheme. When no credentials are available, the GetCredential method returns a null reference (Nothing in Visual Basic).

The following uses GetCredential to retrieve a NetworkCredential instance.
