C # Multithreading

Multithreading:

Thread t = new Thread (new ThreadStart (StartMethod); t. start (); private void StartMethod () {Thread. sleep (5000); MessageBox. show ("c ");}

The multi-thread function is the same as the asynchronous call function. It is used to continue the remaining statements after the called function is run.

ParameterizedThreadStart is a parameter-oriented method. The parameter type is object. StartMethod () is a method without parameters. StartMethod (object I) is a method with parameters. Everyone knows this ~

T. IsBackground = true;

This code means that when the main program is finished, if the code of the supporting thread is not finished, I am sorry ..

At this time, people don't want to talk to the world so early...

Just add t. Join (); at the end of the main program ~.

Why use this. what about invoke? It seems that it is no different from calling a function directly. But if you want to assign a value to the control in the function of the supporting thread, the code will report an error. At this time, this. invoke, this. begininvoke can be used, so that no error is reported.

 

Public void DoWork () {MyInvoke mi = new MyInvoke (Updatetxt); this. beginInvoke (mi, new Object [] {""});} public void Updatetxt (string param) {textBox1.Text = param ;}
