c#实现随鼠标移动窗体
- private void MainForm_Load(object sender, EventArgs e)
- {
- //绑定事件
- MouseMove += Form_MouseMove;
- MouseDown += Form_MouseDown;
- }
- private Point _mousePoint;
- private void Form_MouseMove(object sender, MouseEventArgs e)
- {
- if (e.Button == MouseButtons.Left)
- {
- Top = MousePosition.Y - _mousePoint.Y;
- Left = MousePosition.X - _mousePoint.X;
- }
- }
- private void Form_MouseDown(object sender, MouseEventArgs e)
- {
- if (e.Button == MouseButtons.Left)
- {
- _mousePoint.X = e.X;
- _mousePoint.Y = e.Y;
- }
- }
如果窗体有标题
Top -= SystemInformation.CaptionHeight;
如果有边框
Top -= SystemInformation.FormBorderSize.Height
Left -= SystemInformation.FormBorderSize.Width
