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

public virtual IIdentity RemoteIdentity { get; }
/** @property */
public IIdentity get_RemoteIdentity ()

public function get RemoteIdentity () : IIdentity

Not applicable.

Property Value

An IIdentity object that describes the identity of the remote endpoint.

Exception typeCondition

InvalidOperationException

Authentication failed or has not occurred.

When accessed by the client, this property returns a GenericIdentity containing the Service Principal Name (SPN) of the server and the authentication protocol used. When accessed by the server, this property returns a WindowsIdentity that describes the client. If the WindowsIdentity is not available, client information is returned to the server in a GenericIdentity.

The following code example demonstrates displaying the value of this property.

    public static void EndAuthenticateCallback (IAsyncResult ar)
    {
        // Get the saved data.
        ClientState cState = (ClientState) ar.AsyncState;
        TcpClient clientRequest = cState.Client;
        NegotiateStream authStream = (NegotiateStream) cState.AuthenticatedStream;
        Console.WriteLine("Ending authentication.");
        // Any exceptions that occurred during authentication are
        // thrown by the EndAuthenticateAsServer method.
        try 
        {
            // This call blocks until the authentication is complete.
            authStream.EndAuthenticateAsServer(ar);
        }
        catch (AuthenticationException e)
        {
            Console.WriteLine(e);
            Console.WriteLine("Authentication failed - closing connection.");
            cState.Waiter.Set();
            return;
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            Console.WriteLine("Closing connection.");
            cState.Waiter.Set();
            return;
        }
        // Display properties of the authenticated client.
        IIdentity id = authStream.RemoteIdentity;
        Console.WriteLine("{0} was authenticated using {1}.", 
            id.Name, 
            id.AuthenticationType
            );
        cState.Waiter.Set();
