C#實現點擊表單任意位置拖動

基本思路很簡單：

先得到滑鼠點擊的位置並記錄，滑鼠移動時得到移動後的位置計算出差值，然後平移。

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  {      ///       /// MainWindow.xaml 的互動邏輯      ///       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;              }          }          }  }
