Examples

The following example illustrates how to use the ICredentials interface.

Remarks

The ICredentials interface provides the GetCredential method to objects that supply network credentials to applications.

Methods

GetCredential(Uri, String) GetCredential(Uri, String) GetCredential(Uri, String) GetCredential(Uri, String)

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