推荐答案

我用一个TableLayoutPanel供大家参考（只记得落实code的控制是在前）：

I used a tableLayoutPanel for your reference (Just remember to implement the code to the Control that is in the front):

选项1：复位鼠标位置：

定义两个全局变量：

bool mousemove = true;
Point currentp = new Point(0, 0);

亨德尔MouseDown事件来更新鼠标移动：

private void tableLayoutPanel1_MouseDown(object sender, MouseEventArgs e)
{
    int offsetX = (sender as Control).Location.X + this.Location.X;
    int offsetY = (sender as Control).Location.Y + this.Location.Y;
    mousemove = false;
    currentp = new Point(e.X+offsetX, e.Y+offsetY); //or just use Cursor.Position
}

亨德尔的MouseMove 禁用/启用招：

 private void tableLayoutPanel1_MouseMove(object sender, MouseEventArgs e)
    {
        if (!mousemove)
        {
            this.Cursor = new Cursor(Cursor.Current.Handle);
            Cursor.Position = currentp;
        }
    }

重置鼠标移动，而鼠标松开

private void tableLayoutPanel1_MouseUp(object sender, MouseEventArgs e)
    {
        mousemove = true;
    } 

OPTION2：限制鼠标剪辑矩形：

限制它，而的MouseDown：

Limit it while MouseDown:

private void tableLayoutPanel1_MouseDown(object sender, MouseEventArgs e)
        {            
            this.Cursor = new Cursor(Cursor.Current.Handle);
            Cursor.Position = Cursor.Position;
            Cursor.Clip = new Rectangle(Cursor.Position, new Size(0, 0));
        }

的MouseUp后释放它：

Release it after MouseUp:

 private void tableLayoutPanel1_MouseUp(object sender, MouseEventArgs e)
    {
        this.Cursor = new Cursor(Cursor.Current.Handle);
        Cursor.Position = Cursor.Position;
        Cursor.Clip = Screen.PrimaryScreen.Bounds;
    }
