Restart service at low priority in the third core in C #

After some research I was able to do what I wanted. This code picks up a process, changes the priority to the lowest, and leaves the affinity for only the third CPU core

     Process[] services = Process.GetProcessesByName("WindowsBusinessService");

            try
            {
                //change priority
                services[0].PriorityClass = ProcessPriorityClass.Idle;

                //change affinity
                services[0].ProcessorAffinity = (IntPtr)0x0008;
            }
            catch (Exception)
            {

                Console.WriteLine("ERROR CHANGING PROCESS");
            }

A list of codes to change cores:

       0x1 - 0001 - Core0
       0x2 - 0010 - Core1
       0x3 - 0011 - Core1 & Core0
       0x4 - 0100 - Core2
       0x5 - 0101 - Core2 & Core0
       0x6 - 0110 - Core2 & Core1
       0x7 - 0111 - Core2 & Core1 & Core0
       0x8 - 1000 - Core3
       0x9 - 1001 - Core3 & Core0
       0xA - 1010 - Core3 & Core1
       0xB - 1011 - Core3 & Core1 & Core0
       0xC - 1100 - Core3 & Core2
       0xD - 1101 - Core3 & Core2 & Core0
       0xE - 1110 - Core3 & Core2 & Core1
       0xF - 1111 - Core3 & Core2 & Core1 & Core0

You can try to use the System.Diagnostics namespace to reboot:

foreach(Process proc in Process.GetProcessesByName("nome do processo"))
{
    proc.Kill();
}
Process.Start(@"diretório do serviço");

And to change process priority, use:

foreach(Process proc in Process.GetProcessesByName("nome do processo"))
{
    proc.PriorityClass = ProcessPriorityClass.BelowNormal;
}
