需要添加对 System.Management.dll 的引用

复制代码 代码如下:

using System.Diagnostics;

using System.Management;static void Main(string[] args)

{

foreach (Process p in Process.GetProcesses())

{

Console.Write(p.ProcessName);

Console.Write("----");

Console.WriteLine(GetProcessUserName(p.Id));

}

Console.ReadKey();

}private static string GetProcessUserName(int pID)

{

string text1 = null;

SelectQuery query1 = new SelectQuery("Select * from Win32_Process WHERE processID=" + pID);

ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(query1);

try

{

foreach (ManagementObject disk in searcher1.Get())

{

ManagementBaseObject inPar = null;

ManagementBaseObject outPar = null;

inPar = disk.GetMethodParameters("GetOwner");

outPar = disk.InvokeMethod("GetOwner", inPar, null);

text1 = outPar["User"].ToString();

break;

}

}

catch

{

text1 = "SYSTEM";

}

return text1;

}
