Lesson 7:c# Multithreading

C # Multithreading

1. Applicable to:

Communication over the network

Perform time-consuming actions

Differentiate tasks with different priorities

Enables the user interface to respond quickly to user interactions when performing background tasks

2. common attributes and methods of Thread class

Property:

IsAlive: Show current thread execution status

IsBackground: Whether it is a background process

Name: Gets or sets the thread name

ThreadState: Gets the current thread state

Method:

Thread: constructor, delegate passed to thread when thread is started

Abort: When called, ThreadAbortExceptionis raisedand the thread begins to terminate

Join: blocks the calling thread until a thread terminates

ResetAbort: Cancels abort of the current thread request

Sleep: Sets the number of milliseconds that the thread blocks specified

Start: Begin execution

3, the status of the thread:

4. Start Thread:

1) Create a thread instance:

As shown, invoking the constructor method of the thread class instantiates a thread instance, but the actual thread is not created, at which point the thread is in the unstarted state.

Create thread instances Common: thread t = new Thread (threading method);

and delegate the thread instance to the method of executing the thread: Void Thread method () | | void Threading Method (object)

2) Create thread

T.start ();

T.start (Object obj);

5. Suspend Thread:

thread.sleep (1000);

6. Merging Threads:

You can call the Join method in T1 code if one thread T1 during execution and needs to wait for another thread to finish T2 to continue execution.

For example: T2. Join ();

7. Terminating the thread:

forcibly terminating a thread:. Abort ()

Natural Termination : When the delegate method ends, the thread ends with it.
