C#中是可以呼叫RDP來實現遠端桌面的（AxMSTSCLib.AxMsTscAxNotSafeForScripting），但是如何實現全屏了，讓遠端桌面隨窗體大小一直變化。

            RDP1.Dock = DockStyle.None;
            RDP1.Left = 0;
            RDP1.Top = 0;
            RDP1.Width = Screen.PrimaryScreen.Bounds.Width;
            RDP1.Height = Screen.PrimaryScreen.WorkingArea.Height;
          
            
 
string key = "8位key";
            string iv = "8位iv";
            string ip = Main.IPAddress;
            string user = Main.User;
            string pwd = Main.Pwd;
            this.Text = ip + " : 遠端桌面連線";
            RDP1.Server = ip;
            if (user != "" && pwd != "") {
                pwd
 
=hr.DESDecrypt(pwd,key,iv);
                RDP1.UserName = user;
                IMsTscNonScriptable secured = (IMsTscNonScriptable)RDP1.GetOcx();
                secured.ClearTextPassword = pwd;
            }
            RDP1.Connect();

就可以很方便的實現連線遠端桌面了。
