#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");        }
