Question

I am playing around with threads. I have a question and I think its a very basic one:

I have a class:

Class Message {
   public WriteMsg(string msg)
   {
      Console.Writeline(msg);
   }
}

I create an object of this class

Message msg = new Message();

Now I create ten threads and pass this message object to the function executed by the ten threads. Each will pass its thread index to the writemsg , which will be written out to stdout. I wrote and tested the application and its writing thread index 1 through 10.

As you can see I have not implemented no kind of synchronization. If the class is doing just the functionality mentioned above, do I need a lock mechanism when accessing the object in the threads ?

Answer 1

You need synchronization among threads if they are working working with shared variables.
In your simple example there is no shared variable. So no synch is needed
