C# Maintain 3 threads and close one if it takes to long -

this code using call 3 threads.

for (int = 0; < 3; i++) {     new thread(() => { processeventlogtesting(); }) {isbackground = true }.start(); } 

i thinking adjusting this

public static int threadcounter = 0;  if (threadcounter < 3) {     threadcounter ++;     (int = 0; < 3; i++)     {         new thread(() =>          {             processeventlogtesting(/*somewhere in here code says */threadcounter--;);}) {isbackground = true }.start();         }     } } 

however, think not best way this. also, want put in new timer says if thread x goes on 20 minutes, kill thread x. appreciated.

since don't know thread does, try

        private object lockobject = new object();         private int threadcounter = 0;         public int threadcounter         {                         {                 lock(lockobject)                 {                      return threadcounter;                 }              }                         set             {                 lock(lockobject)                 {                      threadcounter = value;                 }              }         }          //this should method         if (threadcounter < 3)         {             threadcounter ++;             new thread(() =>              {                 timer t = new timer(() => endthread(), null, 0, 20 * 60 * 1000);                 while(threadisrunning)                 {                                           processeventlogtesting(/*somewhere in here code says threadcounter--*/;);                 }             }) {isbackground = true }.start();                  }             }         }          private void endthread()         {             threadisrunning = false;         }
