Question

我正在尝试使用RDP ActiveX控件在C＃中创建一个WinForms RDP客户端作为一个学习练习。当目标服务器不使用网络级别身份验证（NLA）时，我可以使一切正常工作，但是当我尝试将控件配置为使用'EnableCredSspSupport'时，我认为NLA需要它，我在运行时遇到以下错误代码：

未处理的类型异常发生'System.Windows.Forms.AxHost.InvalidActiveXStateException' AxInterop.MSTSCLib.dll

代码是：

        AxMsRdpClient9NotSafeForScripting rdp;

        rdp = new AxMsRdpClient9NotSafeForScripting();

        System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));

        ((System.ComponentModel.ISupportInitialize)(rdp)).BeginInit();
        rdp.Dock = System.Windows.Forms.DockStyle.Fill;
        rdp.Enabled = true;
        rdp.Location = new System.Drawing.Point(0, 0);
        rdp.Name = "rdp";
        rdp.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("rdp.OcxState")));
        rdp.Size = new System.Drawing.Size(828, 687);
        rdp.TabIndex = 0;

        rdp.AdvancedSettings9.AuthenticationLevel = 2;
        rdp.AdvancedSettings9.EnableCredSspSupport = true;

        MainsplitContainer.Panel2.Controls.Add(rdp);

        ((System.ComponentModel.ISupportInitialize)(rdp)).EndInit();

        rdp.Server = "XXX.XXX.XXX.XXX";
        rdp.Connect();

这些代码很多都是从以下来源中篡改过来的，但学习编码通常是站在巨人的肩膀上，对吧！？

......还有更多来源我没有分享的声誉（第一篇文章！）

有什么见解可以帮助我吗？

谢谢！

        _RDPClient.Name = "axMsTscAxNotSafeForScripting1";
        _RDPClient.OcxState = ((System.Windows.Forms.AxHost.State)(_RDPClient.OcxState));
        _RDPClient.Size = new System.Drawing.Size(579, 608);
        _RDPClient.TabIndex = 0;
        _RDPClient.AdvancedSettings8.EnableCredSspSupport = true;
        ((System.ComponentModel.ISupportInitialize)(_RDPClient)).EndInit();

        _RDPClient.OnDisconnected += new IMsTscAxEvents_OnDisconnectedEventHandler(axMsTscAx_OnDisconnected);


        _RDPClient.Server = IP;
        _RDPClient.Connect();

使用：

CType(rdp, System.ComponentModel.ISupportInitialize).EndInit()
rdp.CreateControl()
