Windows远程桌面客户端

1、注册控件：regsvr32 C:\Windows\System32\mstscax.dll。

2、添加RDP Control控件到工具箱中。我选择的RDP Client Control (redistributable) - version 9

3、在VS项目中引用C:\Windows\System32\mstscax.dll

4、RdpTabPage类

using System;
using System.Windows.Forms;

namespace RdpClient
{
    public class RdpTabPage : TabPage
    {
        AxMSTSCLib.AxMsRdpClient9 rdpc = null;
        protected override void OnCreateControl()
        {
            rdpc = new AxMSTSCLib.AxMsRdpClient9();
            rdpc.OnDisconnected += new AxMSTSCLib.IMsTscAxEvents_OnDisconnectedEventHandler(rdpc_OnDisconnected);
            this.Controls.Add(rdpc);
            rdpc.Dock = DockStyle.Fill;
            base.OnCreateControl();
        }

        void rdpc_OnDisconnected(object sender, AxMSTSCLib.IMsTscAxEvents_OnDisconnectedEvent e)
        {
            ((TabControl)this.Parent).TabPages.Remove(this);
        }

        public void Disconnect()
        {
            try
            {
                if (rdpc.Connected == 1)
                {
                    rdpc.Disconnect();
                }
            }
            catch (Exception) { }
        }

        private void SetRdpClientProperties(RdpInfo info)
        {
            rdpc.Server = info.MachineName;
            rdpc.UserName = info.UserName;
            rdpc.Domain = "";
            rdpc.AdvancedSettings9.RDPPort = info.RdpPort;
            rdpc.AdvancedSettings9.ClearTextPassword = info.Password;
            rdpc.AdvancedSettings9.RedirectDrives = true;
            rdpc.AdvancedSettings9.RedirectPrinters = true;
            rdpc.AdvancedSettings9.RedirectSmartCards = true;
            rdpc.AdvancedSettings9.ConnectToServerConsole = true;
            rdpc.ColorDepth = 32;
            rdpc.Dock = DockStyle.Fill;
        }

        public void Connect(RdpInfo info)
        {
            SetRdpClientProperties(info);
            rdpc.Connect();
        }
    }
}

5、主窗体

using System;using System.Windows.Forms;

namespace RdpClient
{
    public partial class Form_Main : Form
    {
        #region 构造
        public Form_Main()
        {
            InitializeComponent();
        }
        #endregion

        #region 方法
        /// <summary>
        /// 绑定远程桌面列表
        /// </summary>
        private void BindMenuItem()
        {
            tsb_Rdps.DropDownItems.Clear();
            if (Config.RdpInfos == null) return;

            foreach (var info in Config.RdpInfos.Items)
            {
                ToolStripMenuItem item = new ToolStripMenuItem();
                item.ImageScaling = ToolStripItemImageScaling.SizeToFit;
                item.Name = string.Format("MenuItem{0}", info.AliasName);
                item.Text = info.AliasName;
                item.Tag = info;
                tsb_Rdps.DropDownItems.Add(item);
            }
        }

        public void RdpConnect(RdpInfo info)
        {
            RdpTabPage rdpTab = new RdpTabPage();
            rdpTab.Text = info.AliasName;

            foreach (TabPage tp in tab_Rdps.TabPages)
            {
                if (tp.Text == rdpTab.Text)
                {
                    tab_Rdps.SelectTab(tp);
                    return;
                }
            }

            tab_Rdps.TabPages.Add(rdpTab);
            rdpTab.Connect(info);
            tab_Rdps.SelectTab(rdpTab);
        }
        #endregion

        }
        private void Form_Main_FormClosing(object sender, FormClosingEventArgs e)
