實現帶參數的多線程的方式

前言

      通常會有需求通過多線程調用帶參數的委托函數,有一個參數的,也有多個參數的,下面來講講實現的方式

執行帶一個參數的委托函數

            #region 執行帶一個參數的多線程
            Thread mythread = new Thread(new ParameterizedThreadStart(Calculate));
            mythread.IsBackground = true;       
            mythread.Start(500);
            #endregion

        private void Calculate(object Max)              //帶一個參數的委托函數  
        {
            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");
        }

執行帶多個參數的委托函數

方式一： 定義一個類,將要傳的參數設置為類的屬性,然后將參數值賦值給類的屬性,將類作為一個參數進行傳達,以下代碼通過兩個參數示例,多個參數一樣,代碼如下

    class MyClass
    {
        public int Max { get; set; }
        public int Min { get; set; }
    }
            #region 第一種方式：執行帶多個參數的多線程
            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)              //帶多個參數的委托函數  
        {
            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表達式的方式,簡單方便,代碼如下：

            #region 第二種方式：執行帶多個參數的多線程
            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)              //帶多個參數的委托函數  
        {
            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");
        }

結束語

        以上就是執行帶參數的多線程的幾種方式,各位看官是否還有更好的方式？？
