C#开发winform窗口实现无边框移动 效果展示： 教程：
创建窗体，选中窗体属性设置BorderStyle = None， 这样窗体就是无边框了 按f7， 将核心移动代码复制到窗体代码后台 将以下代码复制： #region 无边框窗体移动 // 鼠标按下 private bool isMouse = false; // 鼠标是否按下 // 原点位置 private int originX = 0; private int originY = 0; // 鼠标按下位置 private int mouseX = 0; private int mouseY = 0; private void windowMove_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { // 判断鼠标按键 isMouse = true; // 屏幕坐标位置 originX = this.Location.X; originY = this.Location.Y; // 鼠标按下位置 mouseX = originX + e.X; mouseY = originY + e.Y; } } // 鼠标移动 private void windowMove_MouseMove(object sender, MouseEventArgs e) { if (isMouse) { // 移动距离 int moveX = (e.X + this.Location.X) - mouseX; int moveY = (e.Y + this.Location.Y) - mouseY; int targetX = originX + moveX; int targetY = originY + moveY; this.Location = new Point(targetX, targetY); } } // 鼠标释放 private void windowMove_MouseUp(object sender, MouseEventArgs e) { if (isMouse) { isMouse = false; } } #endregion 设置控件鼠标事件：鼠标按下，鼠标移动，鼠标松开
