using System.Diagnostics;using System.Management; 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;
        }
 private void button1_Click(object sender, EventArgs e)
        {
          
            foreach (Process p in Process.GetProcesses())
            {
                Console.Write(p.ProcessName);
                MessageBox.Show(p.ProcessName + "---" + GetProcessUserName(p.Id));            }        }

方法一：使用WMI获取public static string GetProcessInfoByPID(int PID, out string User, out string Domain)
{
    User = String.Empty;
    Domain = String.Empty;
    OwnerSID = String.Empty;
    string processname = String.Empty;
    try
    {
        ObjectQuery sq = new ObjectQuery
            ("Select * from Win32_Process Where ProcessID = '" + PID + "'");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(sq);
        if (searcher.Get().Count == 0)
            return OwnerSID;
        foreach (ManagementObject oReturn in searcher.Get())
        {
            string[] o = new String[2];
            //Invoke the method and populate the o var with the user name and domain
            oReturn.InvokeMethod("GetOwner", (object[])o);            //int pid = (int)oReturn["ProcessID"];
            processname = (string)oReturn["Name"];
            //dr[2] = oReturn["Description"];
            User = o[0];
            if (User == null)
                User = String.Empty;
            Domain = o[1];
            if (Domain == null)
                Domain = String.Empty;
            string[] sid = new String[1];
            oReturn.InvokeMethod("GetOwnerSid", (object[])sid);
            OwnerSID = sid[0];
     return OwnerSID;
        }
    }
    catch
    {
        return OwnerSID;
    }
    return OwnerSID;
}方法二：WIN32API获取，看这里：
