using System.Diagnostics;
using System.Management;
namespace WorkRecord
{
class CurrentUser
{
public static string GetCurrentUser()
{
string currentUser = null;
foreach (Process p in Process.GetProcesses())
{
currentUser = GetProcessUserName(p.Id);
if (currentUser != "SYSTEM" && currentUser != null && currentUser != string.Empty)
break;
}
return currentUser;
}
private static string GetProcessUserName(int pID)
{
string theUser = 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);
theUser = outPar["User"].ToString();
break;
}
}
