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){_mousePoint.X = e.X;_mousePoint.Y = e.Y;} } 如果窗体有标题则改为： Top -= SystemInformation.CaptionHeight; 如果有边框则改为： Top -= SystemInformation.FormBorderSize.HeightLeft -= SystemInformation.FormBorderSize.Width 。

MouseEventArgs e) {if (e.Button == MouseButtons.Left){Top = MousePosition.Y - _mousePoint.Y;Left = MousePosition.X - _mousePoint.X;} } private void Form_MouseDown(object sender， 具体实现方法如下： private void MainForm_Load(object sender，。
