C＃确定远程桌面登录用户的计算机名 [英] C# Determine remote desktop login user's computer name

问题描述

我一直在研究了几个星期，现在，上下车，对如何确定是通过远程桌面登录的用户的计算机名称。

I have been researching for a couple of weeks now, on and off, on how to determine the computer name of the user that is logged in via remote desktop.

我有一个用户在终端服务器环境中运行的应用程序，我想捕获和存储他们使用的是连接到终端服务器的计算机的名称。

I have an application that users run on a terminal server environment, and I would like to capture and store the name of the computer that they are using to connect to the terminal server with.

到目前为止，我还没有能够找到code或创建自己能做到这一点，我想我只是没有提出正确的问题。

So far, I have not been able to find code or create my own that can do this, and I think I am just not asking the right questions.

任何援助将大大AP preciated。

Any assistance would be greatly appreciated.

PS。我使用C＃和.NET 4.0

        }

        private void button1_Click(object sender, EventArgs e)
        {
            WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent());
            MessageBox.Show(wp.Identity.Name); // Username
            MessageBox.Show(GetTerminalServerClientNameWTSAPI()); // Remote Host PC Name

        }

        private static string GetTerminalServerClientNameWTSAPI()
        {

            const int WTS_CURRENT_SERVER_HANDLE = -1;

            IntPtr buffer = IntPtr.Zero;

            string strReturnValue = "";
            try

                WTSQuerySessionInformation(IntPtr.Zero, WTS_CURRENT_SERVER_HANDLE, WTS_INFO_CLASS.WTSClientName, out buffer, out bytesReturned);
                strReturnValue = System.Runtime.InteropServices.Marshal.PtrToStringAnsi(buffer);
            }

            finally
            {
                buffer = IntPtr.Zero;
            }

            return strReturnValue;
        }

        enum WTS_INFO_CLASS
