C# 任务、线程、同步（三）

线程池使用, 线程池中线程均为后台线程

 static void Main()
         {
             int nWorkerThreads;
             int nCompletionPortThreads;
             ThreadPool.GetMaxThreads(out nWorkerThreads, out nCompletionPortThreads);
             Console.WriteLine("Max worker threads: {0}, I/O completion threads: {1}", nWorkerThreads, nCompletionPortThreads);

             for (int i = ; i < ; i++)
             {
                 ThreadPool.QueueUserWorkItem(JobForAThread);

             }

             Thread.Sleep();
         }

         static void JobForAThread(object state)
         {
             for (int i = ; i < ; i++)
             {
                 Console.WriteLine("loop {0}, running inside pooled thread {1}", i,
                    Thread.CurrentThread.ManagedThreadId);
                 Thread.Sleep();
             }

         }

Thread类使用

  static void Main(string[] args)
         {
             //定义、启动线程
             var t1 = new Thread(ThreadMain1);
             t1.Start();
             Console.WriteLine("This is the main thread.{0}",Thread.CurrentThread.ManagedThreadId);

             var t2 = new Thread(() => Console.WriteLine(" running is a thread, id {0}", Thread.CurrentThread.ManagedThreadId));
             t2.Start();
             Console.WriteLine("This is the main thread , id {0}", Thread.CurrentThread.ManagedThreadId);

             //线程传参
             var d = new Data { Message = "Info" };
             var t3 = new Thread(ThreadMainWithParameters);
             t3.Start(d);

             //后台线程
             var t4 = new Thread(ThreadMain2) { Name = "MyNewThread1", IsBackground = true, Priority = ThreadPriority.Highest };
             t4.Start();
             Console.WriteLine("Main thread ending now.");

             Console.Read();
         }

         static void ThreadMain1()
         {
             Console.WriteLine("Running in a thread.{0}", Thread.CurrentThread.ManagedThreadId);
         }
         static void ThreadMainWithParameters(object o)
         {
             Data d = (Data)o;
             Console.WriteLine("Running in a thread ,received {0}", d.Message);
         }
         static void ThreadMain2()
         {
             Console.WriteLine("Thread {0} started", Thread.CurrentThread.Name);
             Thread.Sleep();
             // Console.WriteLine("Running in the thread {0}, id: {1}.", Thread.CurrentThread.Name, Thread.CurrentThread.ManagedThreadId);
             Console.WriteLine("Thread {0} completed", Thread.CurrentThread.Name);
         }

         public struct Data
         {
             public string Message;
         }
