带参数的多线程的方式

#region 执行带一个参数的多线程

            Thread mythread = new Thread(new ParameterizedThreadStart(Calculate));

            mythread.IsBackground = true;       

            mythread.Start(500);

            #endregion



        private void Calculate(object Max)              //带一个参数的委托函数  

        {

            int max = (int)Max;

            Stopwatch stopwatch = Stopwatch.StartNew();

            for (int i = 0; i < max; i++)

            {

                Thread.Sleep(5);

            }

            stopwatch.Stop();

            long lSearchTime = stopwatch.ElapsedMilliseconds;

            MessageBox.Show(lSearchTime.ToString() + "毫秒");

        }

方式一： 定义一个类,将要传的参数设置为类的属性,然后将参数值赋值给类的属性,将类作为一个参数进行传达,以下代码通过两个参数示例,多个参数一样,代码如下

    class MyClass

    {

        public int Max { get; set; }

        public int Min { get; set; }

    }

            #region 第一种方式：执行带多个参数的多线程

            MyClass model = new MyClass();

            model.Max = 500;

            model.Min = 0;

            Thread mythread1 = new Thread(new ParameterizedThreadStart(CalculateTwo));

            mythread1.IsBackground = true;       

            mythread1.Start(model);

            #endregion

        private void CalculateTwo(object Myclass)              //带多个参数的委托函数  

        {

            MyClass model = (MyClass)Myclass;

            Stopwatch stopwatch = Stopwatch.StartNew();

            for (int i = model.Min; i < model.Max; i++)

            {

                Thread.Sleep(5);

            }

            stopwatch.Stop();

            long lSearchTime = stopwatch.ElapsedMilliseconds;

            MessageBox.Show(lSearchTime.ToString() + "毫秒");

        }

方式二：lambda表达式的方式,简单方便,代码如下：

#region 第二种方式：执行带多个参数的多线程

            Thread mythread2 = new Thread(() => CalculateThree(500, 0));

            mythread2.IsBackground = true;        //設置為後臺線程,程式關閉后進程也關閉,如果不設置true，則程式關閉,此線程還在內存,不會關閉

            mythread2.Start(); 

            #endregion

        private void CalculateThree(int Max,int Min)              //带多个参数的委托函数  

        {

            Stopwatch stopwatch = Stopwatch.StartNew();

            for (int i = Min; i < Max; i++)

            {

                Thread.Sleep(5);

            }

            stopwatch.Stop();

            long lSearchTime = stopwatch.ElapsedMilliseconds;

            MessageBox.Show(lSearchTime.ToString() + "毫秒");

        }
