如何从.NET中的Windows服务获取当前登录的用户名？

Question

我有一个需要当前登录用户名的Windows服务.我试过System.Environment.UserName,Windows身份和Windows窗体身份验证,但所有都返回" 系统 "作为用户,因为我的服务在系统特权运行.有没有办法在不更改我的服务帐户类型的情况下获取当前登录的用户名？

Answer 1

这是一个获取用户名的WMI查询:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem");
ManagementObjectCollection collection = searcher.Get();
string username = (string)collection.Cast<ManagementBaseObject>().First()["UserName"];

您需要System.Management手动添加引用.

Answer 2

如果您在用户网络中,则用户名将不同:

Environment.UserName

将显示格式:'用户名',而不是

System.Security.Principal.WindowsIdentity.GetCurrent().Name

将显示格式:'NetworkName\Username'

选择所需的格式.

ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem")解决方案对我来说很好.但是,如果通过远程桌面连接启动服务,则它不起作用.要解决此问题,我们可以要求始终在PC上运行的交互式进程的所有者的用户名:explorer.exe.这样,我们始终从Windows服务获取当前Windows登录的用户名:

foreach (System.Management.ManagementObject Process in Processes.Get())
{
    if (Process["ExecutablePath"] != null && 
        System.IO.Path.GetFileName(Process["ExecutablePath"].ToString()).ToLower() == "explorer.exe" )
    {
        string[] OwnerInfo = new string[2];
        Process.InvokeMethod("GetOwner", (object[])OwnerInfo);

        Console.WriteLine(string.Format("Windows Logged-in Interactive UserName={0}", OwnerInfo[0]));

        break;
    }
}

塔帕斯答案的修改代码:

Dim searcher As New ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem")
Dim collection As ManagementObjectCollection = searcher.[Get]()
Dim username As String
For Each oReturn As ManagementObject In collection
    username = oReturn("UserName")
