c sharp multithreading

1.  静态方法

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
          {
             //创建无参的线程
             //Thread thread1 = new Thread(new ThreadStart(Thread1));
             Thread thread1 = new Thread( (Thread1));
             thread1.Start();
              Console.ReadLine();
          }

          static void Thread1()
           {
               Console.WriteLine("这是无参的方法");
           }
       }
 }

2.实例方法

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
         {
             testThread test = new testThread();
             Thread t1 = new Thread(new ThreadStart(test.fun));
             t1.Start();

             Console.ReadLine();
          }

     }

     class testThread
     {
         public void fun()
         {
             Console.WriteLine("这是实例方法");
         }
     }

 }

简洁写法：

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
         {

             Thread t1 = new Thread(delegate() { Console.WriteLine("匿名委托创建线程"); });
             Thread t2 = new Thread(()=> { Console.WriteLine("lambda创建线程"); Console.WriteLine("hello"); });
             t1.Start();
             t2.Start();
             Console.ReadLine();
          }
     }
 }

3. 带参数实例

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
         {
             Thread t1 = new Thread(new ParameterizedThreadStart(testThread ));
             t1.Start();
             Console.ReadLine();
         }
         static void testThread(object obj)
         {
             Console.WriteLine("带参数实例");
         }
     }
 }

4. 线程基本信息

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
         {
             //获取正在运行的线程
             Thread thread = Thread.CurrentThread;
             //设置线程的名字
             thread.Name = "主线程";
             //获取当前线程的唯一标识符
             int id = thread.ManagedThreadId;
             //获取当前线程的状态
             ThreadState state = thread.ThreadState;
             //获取当前线程的优先级
             ThreadPriority priority = thread.Priority;
             string strMsg = string.Format("Thread ID:{0}\n" + "Thread Name:{1}\n" +
                 "Thread State:{2}\n" + "Thread Priority:{3}\n", id, thread.Name,
                 state, priority);

             Console.WriteLine(strMsg);

             Console.ReadKey();
         }
     }
 }

5. 前后台线程

 using System;
 using System.Threading;

 namespace PlusThread
 {
     class Program
     {
         static void Main(string[] args)
         {
             BgTest bg = new BgTest();
             Thread fThread = new Thread(new ThreadStart(bg.Run));
             fThread.Name = "前台线程";

             BgTest bg1 = new BgTest();
             Thread bThread = new Thread(new ThreadStart(bg1.Run));
             bThread.Name = "后台线程";
             bThread.IsBackground = true;

             fThread.Start();
             bThread.Start();
             Console.ReadLine();
         }
     }

     class BgTest
     {
         private int Count;
         public BgTest(int count)
         {
             this.Count = count;
         }
         public void Run()
         {
             string threadName = Thread.CurrentThread.Name;
             for (int i = ; i < Count; i++)
             {
                 Console.WriteLine("{0}计数：{1}", threadName, i.ToString());
                 Thread.Sleep();
             }
             Console.WriteLine("{0}完成计数", threadName);
         }
     }
 }

            void test()
            {
                for(int i=;i<;i++)
                {
                    textBox1.Text = i.ToString();
                    Thread.Sleep();
                }
            }
        }

        }
        private delegate void setCallBack(int value);
        private setCallBack setcb;
        private void button1_Click(object sender, EventArgs e)
        {
            setcb = new setCallBack(setNum);
            Thread t = new Thread (test);
            t.Start();
            void test()
            {
                for(int i=;i<;i++)
                {
                    textBox1.Invoke(setcb, i);
                }
            }

            void setNum(int i)
            {
                textBox1.Text = i.ToString();
                Thread.Sleep();
            }
        }
    }
}
