C#-线程-start

线程是轻量级进程。一个使用线程的常见实例是现代操作系统中并行编程的实现.

Thread.CurrentThread; 获取当前正在运行的线程。

 

?

static void Main(string[] args)

        {

            Thread th = Thread.CurrentThread;

            th.Name = "MainThread"; // 设置线程的名字

            Console.WriteLine("This is {0}", th.Name); // 获取线程的名字

            Console.ReadKey();

        }

　　[Thread 类常用的属性和方法](https://www.runoob.com/csharp/csharp-multithreading.html)

创建线程

线程是通过扩展 Thread 类创建的。扩展的 Thread 类调用 Start() 方法来开始子线程的执行。

?

1 2	Thread childThread = new Thread(childref); // childref线程要执行的方法的名 childThread.Start();

　　

?

1 2 3 4 5

ThreadStart childref = new ThreadStart(CallToChildThread); // ThreadStart ？ Console.WriteLine("In Main: Creating the Child thread"); Thread childThread = new Thread(childref); childThread.Start(); Console.ReadKey();

　　

管理线程

?

1	Thread.Sleep(5000); // 5000毫秒 = 5s<br>thread.join(); // 阻塞除了thread的线程，先让thread线程执行完，再执行其他的线程

　　

销毁线程

Abort() 方法用于销毁线程。

public static void CallToChildThread()     {         try         {               Console.WriteLine("Child thread starts");             // 计数到 10             for (int counter = 0; counter <= 10; counter++)             {                 Thread.Sleep(500);                 Console.WriteLine(counter);             }             Console.WriteLine("Child Thread Completed");           }         catch (ThreadAbortException e) // 其他线程调用Abort()命令导致该线程被迫中断时，便会进入这里         {             Console.WriteLine("Thread Abort Exception");         }         finally         {             Console.WriteLine("Couldn't catch the Thread Exception");         }       }          static void Main(string[] args)     {         ThreadStart childref = new ThreadStart(CallToChildThread);         Console.WriteLine("In Main: Creating the Child thread");         Thread childThread = new Thread(childref);         childThread.Start();         // 停止主线程一段时间         Thread.Sleep(2000);         // 现在中止子线程         Console.WriteLine("In Main: Aborting the Child thread");         childThread.Abort(); // 因主线程sleep开始的时间是子线程开始执行的时间；故子线程应该也执行了sleep的时间2000毫秒         Console.ReadKey();     } }
