c#获取RDC/RDP和console;会话信息
本文关键字：console 会话 信息 RDP 获取 RDC | 更新日期: 2023-09-27 17:49:02
我试图通过c#以编程方式检索一些RDC/RDP和"控制台"登录信息。
我想开发一个简单的控制台应用程序(. exe)，这样我就可以从任务管理器->用户选项卡的任何远程计算机在我们的域(Windows Server 2003 x86，或2008R2 x64)检索信息。
显示一个人是否直接登录到服务器(即控制台)或通过RDC/RDP(包括客户端，如果它仍然是活动的)或断开连接，如果它是"挂起"(即他们没有注销，但只是暂时关闭RDC/RDP窗口)
我拥有所有服务器的管理员权限，可以配置任何需要启用/禁用的windows服务/防火墙规则(如果需要)
我想我可能要使用WMI(使用System.Management)，但我从谷歌找到的例子只检索现有的用户。
//Method 1
var searcher = new ManagementObjectSearcher(
"SELECT UserName FROM Win32_ComputerSystem");
var collection = Searcher.Get();
foreach(ManagementObject entry in collection)
{
Console.WriteLine(entry["UserName"]);
}
//Method 2
string computer = "somecomputername";
var searcher = new ManagementObjectSearcher(
computer + @"root'CIMV2", "SELECT * FROM Win32_TerminalService");
var collection = Searcher.Get();
foreach(ManagementObject entry in collection)
{
//Write them out (although usernames isnt listed from the example I found)
}
这将为您提供所需的一切。只需调用ListSessions并传入服务器名称。为了获得额外的会话信息，将ServerName和SessionId传递给GetSessionInfo。
