WPF中实现单双击，单双击互斥

 在XAML界面设计器中添加MouseLeftButtonDown事件，或MouseDown事件

 

以下为代码部分：

#region 左击事件（分单双击）
        int i = 0;
        bool 有双击 = false;
        private void Grid_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)   //MouseLeftButtonDown事件
        {
            i += 1;  
            DispatcherTimer timer = new DispatcherTimer();
            timer.Interval = new TimeSpan(0, 0, 0, 0, 200);
            timer.Tick += (s, e1) => { timer.IsEnabled = false; i = 0; 单击(); 有双击 = false; };
            timer.IsEnabled = true;
            if (i % 2 == 0)
            {
                timer.IsEnabled = false;
                i = 0;
                有双击 = true;

                //双击时执行的代码
                //MessageBox.Show("DoubleClick!");
            }            
        }
        private void 单击()
        {
            if (!有双击)
            {

                 //单击时执行的代码
            }
        }
        #endregion

 

第二种办法（看别人的）

private void Grid_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)   //MouseLeftButtonDown事件
        {

            var element = (FrameworkElement)sender;
            if (e.ClickCount == 1)
            {
                var mytimer = new System.Timers.Timer(300);
                mytimer.AutoReset = false;
                mytimer.Elapsed += new ElapsedEventHandler((o, ex) => element.Dispatcher.Invoke(new Action(() =>
                {
                    var timer2 = (System.Timers.Timer)element.Tag;
                    timer2.Stop();
                    timer2.Dispose();
                    //左单击();
                })));
                mytimer.Start();
                element.Tag = mytimer;
            }
            if (e.ClickCount > 1)
            {
                var mytimer = element.Tag as System.Timers.Timer;
                if (mytimer != null)
                {
                    mytimer.Stop();
                    mytimer.Dispose();
                    //左双击();
                }
            }
