C#中远程桌面连接出现奇怪的H_RESULT E_FAIL错误

本文关键字：RESULT 错误 FAIL 程桌面 连接 桌面 | 更新日期: 2023-09-27 17:58:30

我使用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;

这在第一次对远程桌面或终端服务服务器时起作用，但在随后的调用中失败，并出现"H_RESULT E_FAIL"错误，堆栈跟踪在下面。

我如何允许某人从相同的表单重新连接到其他地方（即，在更改属性并尝试connect（）之前，我需要清理什么？）

C#中远程桌面连接出现奇怪的H_RESULT E_FAIL错误

答案很简单。

对Disconnect（）的调用是异步的。

我不得不处理ActiveX控件的OnDisconnect事件，在它触发之前（例如完全断开连接），我不会再次尝试Connect（）。
