Answer questions on your title: multithreaded how to pass parameters? Capture local variables can be completed by means of entrust incoming parameters

Var parameter=123;

Task. Run (()=& gt; {var foo=parameter;//to get parameters});

The Task here. Run and Thread is the same meaning, are open multiple threads, but I recommend using the method of Task, because the Task is a Thread pool
