C # multi-threaded parameter passing

It is very convenient to use C # To create a thread. A Void function can create its own thread application with a statement. See the following example:

 

Simple thread Creation

 public class ThreadController
    {
        public ThreadController()
        {
            System.Threading.Thread thread = new System.Threading.Thread(ThreadMethod);
            thread.Start();
        }

        private void ThreadMethod()
        {
            //Do something
        }
    }

 

However, the preceding example shows that the ThreadMethod method cannot input parameters. To solve this problem, ParameterizedThreadStart is required. Let's look at this example:

 

Parameter thread

 public class ThreadController
    {
        public ThreadController()
        {
            int value = 10;
            System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(ThreadMethod));
            thread.Start(value);
        }

        private void ThreadMethod(object parameter)
        {
            Console.WriteLine(parameter.ToString());
        }
    }

 

 

In this way, the thread response function can receive parameters. There is also a problem to note here, that is, the parameter passed in as the parameter. Although no Ref is added to the parameter description, it is actually a reference of the transfer address. Therefore, if parameter is modified in ThreadMethod. The value in ThreadController is also modified.
