C#WinForm无边框窗体移动方法、模仿鼠标单击标题栏移动窗体位置

这里介绍俩种办法

方法一：直接通过修改窗体位置从而达到移动窗体的效果

方法二：直接伪装发送单击任务栏消息，让应用程序误以为单击任务栏从而移动窗体

新建窗体用于测试

方法一

1.定义一个位置信息Point用于存储鼠标位置

1 private Point mPoint;

2.给窗体等控件增加MouseDown和MouseMove事件

 1 /// <summary> 2 /// 鼠标按下 3 /// </summary> 4 /// <param name="sender"></param> 5 /// <param name="e"></param> 6 private void panel1_MouseDown(object sender, MouseEventArgs e) 7  { 8 mPoint = new Point(e.X, e.Y); 9  }10 11 /// <summary>12 /// 鼠标移动13 /// </summary>14 /// <param name="sender"></param>15 /// <param name="e"></param>16 private void panel1_MouseMove(object sender, MouseEventArgs e)17  {18 if (e.Button == MouseButtons.Left)19  {20 this.Location = new Point(this.Location.X + e.X - mPoint.X, this.Location.Y + e.Y - mPoint.Y);21  }22 }

方法二：

1.引入下面代码前提需要引入命名空间using System.Runtime.InteropServices

1 [DllImport("user32.dll")]2 public static extern bool ReleaseCapture();3 4 [DllImport("user32.dll")]5 public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);6 7 private const int VM_NCLBUTTONDOWN = 0XA1;//定义鼠标左键按下8 private const int HTCAPTION = 2;

2.增加鼠标按下事件发送消息，让系统误以为按下是标题栏

 1 /// <summary> 2 /// 鼠标按下 3 /// </summary> 4 /// <param name="sender"></param> 5 /// <param name="e"></param> 6 private void panel1_MouseDown(object sender, MouseEventArgs e) 7  { 8 //为当前应用程序释放鼠标捕获 9  ReleaseCapture();10 //发送消息 让系统误以为在标题栏上按下鼠标11 SendMessage((IntPtr)this.Handle, VM_NCLBUTTONDOWN, HTCAPTION, 0);12 }
