blocks|key|280928|text|ManagementObjectSearcher(“从Win32_ComputerSystem选择UserName”)解决方案对我来说工作得很好。但如果服务是通过远程桌面连接启动的，则不起作用。要解决此问题，我们可以询问始终在PC上运行的交互进程的所有者的用户名:+explorer.exe。这样，我们始终可以从Windows服务中获得当前Windows登录的用户名：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|280929|foreach+(System.Management.ManagementObject+Process+in+Processes.Get())

ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem") solution worked fine for me. BUT it does not work if the service is started over a Remote Desktop Connection.
To work around this, we can ask for the username of the owner of an interactive process that always is running on a PC: explorer.exe. This way, we always get the currently Windows logged-in username from our Windows service:

<pre><code>foreach (System.Management.ManagementObject Process in Processes.Get())
{
 if (Process["ExecutablePath"] != null &amp;&amp; 
 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;
 }
}
</code></pre>

If you are in a network of users, then the username will be different:

<pre><code>Environment.UserName
</code></pre>

Will Display format : 'Username',
rather than

<pre><code>System.Security.Principal.WindowsIdentity.GetCurrent().Name
</code></pre>

Will Display format : 'NetworkName\Username'

Choose the format you want.

Add Reference to <code>System.DirectoryServices.AccountManagement</code> in your project.

I have a Windows service which need the currently logged username. I tried <code>System.Environment.UserName</code>, Windows identity and Windows form authentication, but all are returning "System" as the user as my service is running in system privileged. Is there a way to get the currently logged in username without changing my service account type?

How do I get the currently-logged username from a Windows service in .NET?

身份验证

Windows

我有一个需要当前登录用户名的Windows服务。我尝试了System.Environment.UserName、Windows identity和Windows form身份验证，但都以用户身份返回" system “，因为我的服务是在系统特权下运行的。有没有办法在不更改我的服务帐户类型的情况下获得当前登录的用户名？
