如何制作屏幕共享应用程序

Question

我正在尝试在 C# 中制作一个简单的屏幕共享应用程序并找到了本指南：https ://www.c-sharpcorner.com/uploadfile/ulricht/how-to-create-a-simple-screen-sharing-application-in -C-Sharp/并跟随它，但它不起作用 我在同一台计算机和两台不同的 PC 上尝试过它，但似乎没有任何效果

//Host

public partial class ScreenShareHandler : Form

    {

        RDPSession x = new RDPSession();

        public ScreenShareHandler()

        {

            InitializeComponent();

        }

        private void ScreenShareHandler_Load(object sender, EventArgs e)

        {

        }

        private void Incoming(object Guest)

        {

            IRDPSRAPIAttendee MyGuest = (IRDPSRAPIAttendee)Guest;//???

            MyGuest.ControlLevel = CTRL_LEVEL.CTRL_LEVEL_INTERACTIVE;

        }

        private void button1_Click(object sender, EventArgs e)

        {

            x.OnAttendeeConnected += Incoming;

            x.Open();

        }

        private void button2_Click(object sender, EventArgs e)

        {

            IRDPSRAPIInvitation Invitation = x.Invitations.CreateInvitation("Trial", "MyGroup", "", 10);

            textBox1.Text = Invitation.ConnectionString;

        }

        private void button3_Click(object sender, EventArgs e)

        {

            x.Close();

            x = null;

        }

    }

//Client

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

        }

        private void button1_Click(object sender, EventArgs e)

        {

            string Invitation = textBox1.Text;// "";// Interaction.InputBox("Insert Invitation ConnectionString", "Attention");

            axRDPViewer1.Connect(Invitation, "User1", "");

        }

        private void button2_Click(object sender, EventArgs e)

        {

            axRDPViewer1.Disconnect();

        }

}
