How do I get the mouse position? I want it in term of screen position.

I start my program I want to set to the current mouse position.

Location.X = ??
Location.Y = ??

Edit: This must happen before the form is created.

Cursor.Position will get the current screen poisition of the mouse (if you are in a Control, the MousePosition property will also get the same value).

To set the mouse position, you will have to use Cursor.Position and give it a new Point:

Cursor.Position = new Point(x, y);

You can do this in your Main method before creating your form.

To answer your specific example:

// your example
Location.X = Cursor.Position.X;
Location.Y = Cursor.Position.Y;

// sample code
Console.WriteLine("x: " + Cursor.Position.X + " y: " + Cursor.Position.Y);

Don’t forget to add using System.Windows.Forms;, and adding the reference to it (right click on references > add reference > .NET tab > Systems.Windows.Forms > ok)

If you need to get current position in form’s area (got experimentally), try the following:

Console.WriteLine(
    "Current mouse position in form's area is " + 
    (Control.MousePosition.X - this.Location.X - 8).ToString() +
    "x" + 
    (Control.MousePosition.Y - this.Location.Y - 30).ToString()
);

Although, 8 and 30 integers were found while experimenting. It’d be awesome if someone could explain why exactly these numbers worked.

Also, there’s another variant (considering code is in a form’s code-behind):

Point cp = PointToClient(Cursor.Position); // Get cursor's position according to form's area
Console.WriteLine("Cursor position: X = " + cp.X + ", Y = " + cp.Y);

   internal static class CursorPosition {
  [StructLayout(LayoutKind.Sequential)]
  public struct PointInter {
     public int X;
     public int Y;
     public static explicit operator Point(PointInter point) => new Point(point.X, point.Y);       
  }

  [DllImport("user32.dll")]
  public static extern bool GetCursorPos(out PointInter lpPoint);

  // For your convenience
  public static Point GetCursorPosition() {
     PointInter lpPoint;
     GetCursorPos(out lpPoint);
     return (Point) lpPoint;
  }

}

Initialize the current cursor.
Use it to get the position of X and Y

this.Cursor = new Cursor(Cursor.Current.Handle);
int posX = Cursor.Position.X;
int posY = Cursor.Position.Y;
