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
)

Parameters

uri
Type: System::Uri

The Uri that the client is providing authentication for.

authType
Type: System::String

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

Return Value

Type: System.Net::NetworkCredential
The NetworkCredential that is associated with the specified URI and authentication type, or, if no credentials are available, nullptr.

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 nullptr.

The following uses GetCredential to retrieve a NetworkCredential instance.
