1. Thread线程启动
由于ThreadStart是一个委托，所以可以简化写法
static void Main(string[] args) { Console.WriteLine("----------主程序开始，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); for(int i = 0;i< 5;i++) { ThreadStart method = () => TestThread("无参数"); Thread thread = new Thread(method); thread.Start(); } Console.WriteLine("----------主程序结束，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); Console.Read(); } static void TestThread(string name) { Console.WriteLine("TestThread Start name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); long sum = 0; for (int i = 0; i < 10000000; i++) { sum += i; } Console.WriteLine("TestThread End name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); }
2. Thread线程传递参数
上面的例子没专递没有参数的，现在开始传递参数
public delegate void ParameterizedThreadStart(object obj);
这个是Thread可以传递参数的方法委托，使用这个委托，可以传递参数。
static void Main(string[] args) { Console.WriteLine("----------主程序开始，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); for(int i = 0;i< 5;i++) { ParameterizedThreadStart method = o => TestThread(o.ToString()); Thread thread = new Thread(method); thread.Start("param" + i); } Console.WriteLine("----------主程序结束，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); Console.Read(); } static void TestThread(string name) { Console.WriteLine("TestThread Start name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); long sum = 0; for (int i = 0; i < 10000000; i++) { sum += i; } Console.WriteLine("TestThread End name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); }
3. Thread线程等待
有时候，主线程需要等待子线程执行完后在执行，Thread的线程等待我们使用join()来实现
static void Main(string[] args) { Console.WriteLine("----------主程序开始，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); List<Thread> list = new List<Thread>(); for(int i = 0;i< 5;i++) { ParameterizedThreadStart method = o => TestThread(o.ToString()); Thread thread = new Thread(method); thread.Start("param" + i); list.Add(thread); } foreach (var t in list) { t.Join(); } Console.WriteLine("----------主程序结束，线程ID是{0}-----------------", Thread.CurrentThread.ManagedThreadId); Console.Read(); } static void TestThread(string name) { Console.WriteLine("TestThread Start name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); long sum = 0; for (int i = 0; i < 10000000; i++) { sum += i; } Console.WriteLine("TestThread End name:{0} 当前线程id:{1} 当前时间:{2}", name, Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString()); }
4. Thread线程获取返回值
Thread没发获取返回值，请注意
5. Thread线程回调
Thread没有回调，我们自定义一个回调
private void ThreadCallBack(ThreadStart method, Action callback) { ThreadStart threadStart = () => { method.Invoke(); callback.Invoke(); }; Thread thread = new Thread(threadStart); thread.Start(); }
