c#检查网络上登录的用户

Question

如何查询网络中的所有 PC 以查看实际登录的用户。我需要获取“IPAddress + LogedUserName”列表。

我正在通过这种方式获取 LAN 上可用的计算机列表:

using (DirectoryEntry root = new DirectoryEntry("WinNT:"))
        {
            foreach (DirectoryEntry computers in root.Children)
            {
                foreach (DirectoryEntry computer in computers.Children)
                {
                    if ((computer.Name != "Schema"))
                    {
                        textBox1.Text += computer.Name + "\r\n";
                    }
                }
            }
        }

但我还想在每台可用计算机上拥有登录用户的名称。

既然你的问题在这里被重新提出来了，那么关于使用 cassia 的更完整的解释.这可能适用于也可能不适用于未启用 RemoteDesktop 的桌面。此代码完全未经测试，可能需要一些修复才能 100% 运行，但它会让您走上正轨。

using (DirectoryEntry root = new DirectoryEntry("WinNT:"))
{
    ITerminalServicesManager tsm = new Cassia.TerminalServicesManager();

    foreach (DirectoryEntry computers in root.Children)
    foreach (DirectoryEntry computer in computers.Children)
    {
        if ((computer.Name != "Schema"))
        {
            string linqCapture = computer.Name; //<-- This may not be necessary, 
                                                //but I have always have had bad
                                                //experiences with LINQ and foreach
                                                //loops not capturing the current
                                                //value of the variable correctly.

            //remove the last Where clause if you want all users connected 
            //to the computer, not just the one where it is the console session.
            foreach(var session in tsm.GetSessions(linqCapture)
                                      .Where(s => s.ConnectionState == ConnectionState.Active)
                                      .Where(s => s.ClientName == linqCapture))
            {
                string LoggedInUser = session.UserName;
                System.Net.IPAddress LoggedInIp = session.ClientIPAddress;
                //Do with data what ever you want to;
            }
        }
    }
}
