本文介绍了一个简单的双击检测实现方案，通过开启线程并利用超时机制来判断是否完成连续两次点击操作。该方案适用于需要区分单击和双击场景的应用开发。

网友做的一个双击的例子

原理是
第一次点击开一个线程(sheep 200 且 lock)
如果在200ms内再点击线程继续sheep 200 统计点击次数
...........
............
timeout 后
线程执行比较传入的要求点击数与统计点击的次数
true 的话就执行

public class MClick
    {
        public static void MulClick(int count, MouseButtonEventHandler handle, object sender, MouseButtonEventArgs e)
        {
            bolClicking = true;
            if (bolClicked)
            {
                intClickCount++;
            }
            else
            {
                bolClicked = true;
                intCount = count;
                handleClick = handle;
                objSender = sender;
                mbeE = e;
                asyncOperation = AsyncOperationManager.CreateOperation(null);
                objThreadLock = new object();
                Thread thread = new Thread(ResetThread);
                thread.Start();
                while (!thread.IsAlive) ;
            }
        }

        private static int intTimeOut = 200;
        public static int TimeOut
        {
            get
            {
                return intTimeOut;
            }

            set
            {
                intTimeOut = value < 1 ? 1 : value;
            }
        }

        private static int intCount;
        private static object objSender;
        private static MouseButtonEventArgs mbeE;
        private static MouseButtonEventHandler handleClick;
        private static int intClickCount = 0;
        private static bool bolClicked = false;
        private static bool bolClicking = false;
        private static object objThreadLock;
        private static AsyncOperation asyncOperation;

        private static void ResetThread()
        {
            while (bolClicking)
            {
                bolClicking = false;
                Thread.Sleep(TimeOut);
            }

            lock(objThreadLock)
            {
                if (intCount == ++intClickCount)
                {
                    asyncOperation.Post(callback, objSender);
                }

                intClickCount = 0;
                bolClicked = false;
            }

}

        private static void callback(object state)
        {
            handleClick(objSender, mbeE);
        }
    }

============================
只是测试性，满乱的~~哈哈。有兴趣的朋友可以改进~
改成
MulClick(点击次数, 控件, 函数)

使用
==============================
        public Page()
        {
            InitializeComponent();
            LayoutRoot.MouseLeftButtonUp += new MouseButtonEventHandler(HandleClick);
        }

        private void HandleClick(object sender, MouseButtonEventArgs e)
        {

            //MClick.MulClick(1, onClick, sender, e);

MClick.MulClick(2, onDoubleClick, sender, e);

}

        private void onClick(object sender, MouseButtonEventArgs e)
        {
            txtMsg.Text = "单击";
        }

        private void onDoubleClick(object sender, MouseButtonEventArgs e)
        {
            txtMsg.Text = "双击";
        }
    }
