C # .Net how to get the relative coordinates when the mouse clicks on the form ???

For example: There is a form of Form1. At runtime. Use your mouse to click anywhere on the Form1 form. To get the relative coordinates of the mouse on the form ??? (note: not the screen coordinates of the mouse click)

It is recommended to use JS to achieve.

In the WinForm program, you can use the system.Windows.Forms.Form.MousePosition property to get the mouse, and then subtract the coordinates of the point obtained from the position of the form (Location property) to be the relative position of the mouse.

holy1027: Thank you very much. . .
I used your method. But there is a shortcoming. It is when the mouse is pressed to drag the form. If the mouse moves too fast. The movement of the form will not keep up. . .
Is there a good solution in this regard? ? ?

If you are in the mouse movement event processing function, you can get it directly
        private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            int MousePositionX = e.X
        }
