Change Process priority does not work

Question

I run an Audio Repeater application which allows me to play sound through my headset & Speakers at the same time. The Application itself has an ability to set itself to \"Re

Answer 1

Try this :

using (Process p = Process.GetCurrentProcess())
    p.PriorityClass = ProcessPriorityClass.High;  

Answer 2

You need to run YOUR script with administrative privilege.

Answer 3

You can run as an administrator or remove UAC because you need rights to access to a Process you did not run.

This works for me :

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

// #define DEBUG

namespace ProcessRealtime
{
    class PUBG_RealTime
    {
        static string processName = "TslGame";
        static ProcessPriorityClass newPriority = ProcessPriorityClass.High;

        static void Main(string[] args)
        {
#if DEBUG
            PutDebug("Start!");
#endif
            Process[] processes = Process.GetProcessesByName(processName);
#if DEBUG
            PutDebug(processes.Length + " processed found");
#endif
            foreach (Process proc in processes)
            {
#if DEBUG
                PutDebug("New process found");
#endif
                Console.WriteLine("Changing Priority for id:" + proc.Id + " to " + newPriority.ToString());
                proc.PriorityClass = newPriority;
#if DEBUG
                PutDebug("Changed priority for " + proc.Id);
#endif
            }
#if DEBUG
            PutDebug("No more processes..");
#endif
            Console.Write("Press a key, it's over !");
            Console.ReadLine();
        }

#if DEBUG
        static bool debug = true;
        static int debugInc = 1;
        static void PutDebug(string info = "")
        {
            if(debug){
                Console.WriteLine("Debug" + debugInc + ": " + info);
                debugInc++;
            }
        }
#endif
    }
}
