c# - Wake up a thread when event occurs -

-

i achieve following communication between 2 threads:

thread alpha something, , suspends itself. next second thread(beta) raises , event resumes alpha thread. cycle goes on...

i did below not sure if proper design. i've notice thread.suspend() , thread.resume() deprecated. i'm looking forward hearing advice implementation , preferred replace deprecated methods.

namespace threadtester {     delegate void actionhandler();      class alpha     {         internal thread alphathread;         internal void start()         {             while (true)             {                 this.alphathread.suspend();                 console.writeline("alpha");             }         }         internal void resume()         {             while (this.alphathread.threadstate == threadstate.suspended)             this.alphathread.resume();         }     }      class beta     {         internal event actionhandler onevent;         internal void start()         {             (int = 0; < 15; i++)             {                 onevent();                 thread.sleep(1000);             }         }     }      class program     {         static void main(string[] args)         {             alpha alpha = new alpha();             alpha.alphathread = new thread(new threadstart(alpha.start));             alpha.alphathread.start();             while (!alpha.alphathread.isalive) ;              beta beta = new beta();             beta.onevent += new actionhandler(alpha.resume);             thread betathread = new thread(new threadstart(beta.start));             betathread.start();         }     } }

typically threads used allow > 1 item of work processed in parallel. i'm curious why design requires thread sleep while thread b something, wake , carry on working. why not have thread work itself?

you might benefit using .net 4's task parallel library - thread initiate asynchronous task automagically executed on separate thread, , result made available thread without need explicit inter-thread signalling (which can result in hung app if either thread or b malfunctions).
