下面的代码示例演示如何使用此属性。

public static void ShowRequestProperties2 (HttpListenerRequest request)

    Console.WriteLine("Local end point: {0}", request.LocalEndPoint.ToString());
    Console.WriteLine("Remote end point: {0}", request.RemoteEndPoint.ToString());
    Console.WriteLine("Is local? {0}", request.IsLocal);
    Console.WriteLine("HTTP method: {0}", request.HttpMethod);
    Console.WriteLine("Protocol version: {0}", request.ProtocolVersion);
    Console.WriteLine("Is authenticated: {0}", request.IsAuthenticated);
    Console.WriteLine("Is secure: {0}", request.IsSecureConnection);
}

Public Shared Sub ShowRequestProperties2(ByVal request As HttpListenerRequest)
    Console.WriteLine("KeepAlive: {0}", request.KeepAlive)
    Console.WriteLine("Local end point: {0}", request.LocalEndPoint.ToString())
    Console.WriteLine("Remote end point: {0}", request.RemoteEndPoint.ToString())
    Console.WriteLine("Is local? {0}", request.IsLocal)
    Console.WriteLine("HTTP method: {0}", request.HttpMethod)
    Console.WriteLine("Protocol version: {0}", request.ProtocolVersion)
    Console.WriteLine("Is authenticated: {0}", request.IsAuthenticated)
    Console.WriteLine("Is secure: {0}", request.IsSecureConnection)
End Sub
