This class maintains credentials for multiple network resources. If you are developing a client application that needs to authenticate itself to more than one server, you can store an instance of this class in the WebRequest.Credentials property.

After you create an instance of this class, use the Add( ) method to associate NetworkCredential objects with a URI and authentication type (using a string such as "Basic" or "Digest"). Then you can assign the CredentialCache instance to the WebRequest.Credentials property to use the credentials for future web requests.

public class CredentialCache : ICredentials, IEnumerable {
// Public Constructors
   public CredentialCache( );
// Public Static Properties
   public static ICredentials DefaultCredentials{get; }
// Public Instance Methods
   public void Add(Uri uriPrefix, string authType, NetworkCredential cred);
   public NetworkCredential GetCredential(Uri uriPrefix, string authType)
// implements ICredentials
   public IEnumerator GetEnumerator( );   
// implements IEnumerable
   public void Remove(Uri uriPrefix, string authType);
