从远程登录用户获取计算机名称。

如果没有关于您的应用程序的任何信息，我只能假设您想要运行外部程序并查找任何连接的计算机的 DNS 名称。 我将完成我将采取的步骤：

首先，我使用命令行参数“-a”启动进程“netstat”。 重定向输出以便您可以阅读它：

Process netStat = new Process();
netStat.StartInfo.UseShellExecute = true;
netStat.StartInfo.CreateNoWindow = true;
netStat.StartInfo.FileName = "netstat";
netStat.StartInfo.Arguments ="-a";
netStat.StartInfo.RedirectStandardOutput = true;

netStat.Start();   //Can take several seconds to execute, good use for BackgroundWorker

string output = netStat.StandardOutput.ReadToEnd();

现在您已拥有连接到计算机的所有内容（输入和输出）的数据。 您可以在控制台窗口中运行 netstat 命令来查看输出。 然后，您可以按行拆分以获取每个条目，然后再次按选项卡拆分以获取每个列。 您对第三列感兴趣，其中包含计算机名称：端口或 IP 地址：端口（如果无法确定名称）。

你好 ：）

不是我的代码，只是针对 x64 版本进行了修改（也许对多年后的某人有帮助）。 仅用于获取当前 RDP（远程桌面）客户端主机名。
