WinForms ActiveX RDP Client Issue With NLA

Question

我正在尝试使用RDP ActiveX控件在C#中制作WinForms RDP客户端作为学习练习。当目标服务器不使用网络级别身份验证 （NLA） 时，我可以让一切正常工作，但是当我尝试将控件配置为使用我认为 NLA 需要的"EnableCredSspSupport"时，我在运行代码时出现以下错误：

类型的未处理异常 "System.Windows.Forms.AxHost.InvalidActiveXStateException"发生在 AxInterop.MSTSCLib.dll

代码为：

        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();

很多代码都是从以下来源拼凑在一起的，但学习编码通常是站在巨人的肩膀上，对吧！？

。还有一些我没有声誉可以分享的来源（第一篇文章！

有什么见解可以帮助我吗？

谢谢！

....Aaaand工作代码：

            AxMSTSCLib.AxMsRdpClient8NotSafeForScripting _RDPClient;
        _RDPClient = new AxMSTSCLib.AxMsRdpClient8NotSafeForScripting();
        MainsplitContainer.Panel2.Controls.Add(_RDPClient);
        ((System.ComponentModel.ISupportInitialize)(_RDPClient)).BeginInit();
        _RDPClient.Dock = System.Windows.Forms.DockStyle.Fill;
        _RDPClient.Enabled = true;
        _RDPClient.Location = new System.Drawing.Point(0, 0);
        _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()

在 C# 中查找等效项
