Winform去掉标题栏后移动窗体

第一步：声明全局变量->  private Point _HoverTreePosition;

第二步：

#region 隐藏标题栏后移动窗口
private void Form_HoverTree_MouseDown(object sender, MouseEventArgs e)
{
_HoverTreePosition.X = e.X;
_HoverTreePosition.Y = e.Y;
}

private void Form_HoverTree_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
Point h_myPosittion = MousePosition;
h_myPosittion.Offset(-_HoverTreePosition.X, -_HoverTreePosition.Y);
Location = h_myPosittion;
}
}
#endregion

第三步：在窗体上绑定MouseDown、MouseMove两个方法
