如何从 C# 线程到 object 哪个成员 function 是该线程的参数？

Question

In C# threads are created by passing a member function:

class SomeClass {
   public void ThreadFunction() {Thread.Sleep( Infinite ); }
};


SomeClass myObject = new SomeClass();
Thread thread = new Thread( myObject.ThreadFunction );
thread.Start();

Here ThreadFunction() is not static, so I guess the object reference is passed to Thread constructor.

How can code inside ThreadFunction() get to myObject ? Do I just use this reference for that?

Answer 1

In the exact example you give, simply by accessing this .

In the general case, you can also do something like

class SomeClass {
   public void ThreadFunction(object param)
   {
     var justAnExample = (string)param;
   }
};


SomeClass myObject = new SomeClass();
Thread thread = new Thread(myObject.ThreadFunction);
thread.Start("parameter");

This allows you to pass a parameter of any type (here, a string ) to the thread function. If you need more than one, then you can always pass in a Tuple or an object[] or any other container of values.

If you go this way, you might want to make ThreadFunction static (this will lose you the option of using this ) as well.

Like this:

class SomeClass {
  public void ThreadFunction(Object obj) 
  {
    SomeClass myObject = (SomeClass)obj;
    Thread.Sleep( Infinite ); 
  }
};


SomeClass myObject = new SomeClass();
Thread thread = new Thread(new ParameterizedThreadStart(myObject.ThreadFunction) );
thread.Start(myObject)
