How to: Get the Current Mouse Position (Windows)

This example demonstrates how to get the current horizontal and vertical position of the mouse cursor relative to the upper-left corner a game window.

The example queries the Mouse class to return a MouseState object that holds the button states and the current position of the mouse relative to the upper-left corner of the game window.

To retrieve the current mouse position

1. Call GetState to get the current state of the mouse in a MouseState object.
2. Access the X and Y properties of the MouseState retrieved in the previous section to get the X (horizontal) and Y (vertical) mouse position, in pixels, relative to the upper-left corner of the game window.
