C # using anonymous delegation to simplify thread and controle. Invoke writing

1. Thread
C # in the program, if you want to create a new thread, you usually need to create another method. If you want to pass parameters, the steps are troublesome,
Reference 1
Thread othread = new thread (New threadstart (threadmethod ));
Private void threadmethod (){
..
};

If you want to pass parameters to the thread

Public static void mystaticparamthreadmethod (Object OBJ ){
Console. writeline (OBJ );
}

Thread thread = new thread (mystaticparamthreadmethod );
Thread. Start (OBJ );

Of course, there are other writing methods. For more information, see reference 1.

However, if you use an anonymous class, it will be simpler.

Thread othread = new thread (delegate ()
{
....
});
Othread. Start ();

2. Control. Invoke

In C #, if you call multiple threads to update the UI attributes, an exception is reported: Cross-thread operation not valid.

The general solution is to declare a delegate and call it through the delegate. For details, refer to 2.

Private delegate void flushclient (); // proxy

Private void threadfunction ()
{
If (textbox1.invokerequired) // wait for Asynchronization
{
Flushclient fc = new flushclient (threadfunction );
This. Invoke (FC); // call the refresh method through the proxy
Return;
}
Textbox1.text = datetime. Now. tostring ();
}

Here, we need to declare a delegate first, which is quite troublesome, because we always need to write more delegates, but these delegates are a temporary transition. After being changed to an anonymous delegate, we do not need to declare those delegates.

Private void threadfunction ()
{
If (textbox1.invokerequired) // wait for Asynchronization
{
This. Invoke (New methodinvoker (delegate ()
{
Threadfunction ();
}));
Return;
}
Textbox1.text = datetime. Now. tostring ();
}

The amount of code is not reduced, but you do not have to declare the temporary delegate.
