C#實現點擊窗體任意位置拖動

基本思路很簡單：

先得到鼠標點擊的位置并記錄，鼠標移動時得到移動后的位置計算出差值，然后平移。

代碼：

    using System;

    using System.Collections.Generic;

    using System.Linq;

    using System.Text;

    using System.Windows;

    using System.Windows.Controls;

    using System.Windows.Data;

    using System.Windows.Documents;

    using System.Windows.Input;

    using System.Windows.Media;

    using System.Windows.Media.Imaging;

    using System.Windows.Navigation;

    using System.Windows.Shapes;

    namespace DragWindowTest

    {

        /// <summary>

        /// MainWindow.xaml 的交互邏輯

        /// </summary>

        public partial class MainWindow : Window

        {

            public MainWindow()

            {

                InitializeComponent();

            }

            private static bool IsDrag = false;

            private double enterX;

            private double enterY;

            private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

            {

                IsDrag = true;

                enterX = e.GetPosition(this).X;

                enterY = e.GetPosition(this).Y;

            }


        private void Window_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)  
        {  
            IsDrag = false;  
            enterX = 0;  
            enterY = 0;  
        }  
        private void Window_MouseMove(object sender, MouseEventArgs e)  
        {  
            if (IsDrag)  
            {  
                this.Left += e.GetPosition(this).X - enterX;  
                this.Top += e.GetPosition(this).Y - enterY;  
            }  
        }  

    }  
}  </pre>
