我正在使用 C# 中的 com 组件 Microsoft RDP Client Control 版本 8 连接到终端服务器和远程桌面。

代码看起来像这样：

if (rdp.Connected.ToString() == "1")
{
  rdp.Disconnect();
}
rdp.Server = userDetails.RoleMachine;
rdp.UserName = userDetails.UserName;
IMsTscNonScriptable secured = (IMsTscNonScriptable)rdp.GetOcx();
secured.ResetPassword();
secured.ClearTextPassword = userDetails.Password;

这第一次适用于远程桌面或终端服务服务器，但在后续调用中失败并出现“H_RESULT E_FAIL”错误，下面的堆栈跟踪。

如何允许某人从同一表单重新连接到其他地方（即在更改属性和尝试 connect() 之前我需要清理什么？）

答案很简单。

对 Disconnect() 的调用是异步的。

我必须处理 ActiveX 控件的 OnDisconnect 事件，而不是在它触发之前再次尝试 Connect()，例如完全断开连接。
