"Multithreaded" Task

"Multithreaded" Task

A. Common methods:

1. ContinueWith: When the current task completes, the incoming task is executed

2. Delay: Creates a waiting Task that is blocked only when the wait method is called (note: different from Thread.Sleep)

3. Run: Create a Task and execute

4. Start: Execute Task

5. Wait: Blocks the thread for a certain amount of time until the Task completes or the wait time is exceeded

6. WaitAll: Blocking threads until all tasks have completed or exceeded wait time

7. WaitAny: Blocking threads until one Task completes or waits longer

Two. Common Properties:

1. Factory: Get the factory used to create the task, create a task with

2. Status of the Status:task

Three. Syntax

   Private Static voidMain (string[] args) {Console.WriteLine (DateTime.Now+"Start"); Task T1= Task.Factory.StartNew (dotask). ContinueWith (Continuetask);//Create a Task execution Dotask, Dotask execute continuetask after completionTask t2 =Task.Factory.StartNew (dotask); Task.waitany (New[] {t1, t2}, +); Console.WriteLine (DateTime.Now+"WaitAny Timeout 1 seconds"); Task.waitall (New[] {t1, t2},Ten* +); Console.WriteLine (DateTime.Now+"WaitAll timeout 10 seconds"); T1. Wait ( -* +);//Note: t here refers to ContinueWith, not StartNew, which is the final Task of the expressionConsole.WriteLine (DateTime.Now +"wait T1 timeout 50 seconds");        Console.ReadLine (); }        Private Static voidDotask () {Task.delay (3* +). Wait ();//blocked for 3 seconds, only valid after WaitConsole.WriteLine (DateTime.Now +"Dotask finished, worked for 3 seconds"); }        Private Static voidContinuetask (Task Task) {Task.delay (4* +). Wait ();//blocked for 4 seconds, only valid after WaitConsole.WriteLine (DateTime.Now +"Continuetask completed and worked for 4 seconds after dotask."); }
