我确实解决了！！！
解释
我意识到我需要的是会话 ID（环境）以某种方式获取登录用户名（上下文的所有者）。
获取会话 ID 非常简单：
int session = System.Diagnostics.Process.GetCurrentProcess().SessionId;
到这个时候，我的目标是让用户名链接到这个会话，然后我发现了这个
从 SessionID 获取 Windows 用户名
现在，使用用户名，我认为很容易检查该用户名是否属于管理员组。我错了。我发现需要使用 wmi 和 pinvoke 的最简单方法。
主要问题是，为了进行查询，我必须知道当前操作系统中管理员组的名称，即取决于语言。
解决方案是这样的：
http://www.pinvoke.net/default.aspx/advapi32.lookupaccountsid
我调整了代码，将所有部分放在一起，就是这样。
总结一下，我找到了 sessionid，找到了链接到 session 的用户名，找到了 OS Administrators 组名，并做了一些 Wmi 查询来检查用户是否是管理员。
这个解决方案对我来说很好，但我必须说运行速度很慢。
如果有人可以改进此代码，或者如果它对其他人有用，我就把它留在这里。
只要记住添加对 System.Management 的引用即可；我使用了 Visual Studio C# Express 2010。该项目是一个 Windows 窗体应用程序。
快乐编码！！！
