Is there a function to determine the relationship between a point and a rectangle?

private Rectangle boundRect;

private Region testRegion;

private Point testPoint;

private bool IsInRect;

private bool IsInRegion;

private void TestHitDetection()
{
    boundRect = this.ClientRectangle;

    testRegion = new Region(new Rectangle(50,50, 200,200));

    testPoint = new Point(100,100);

    IsInRect = boundRect.Contains(testPoint);

    IsInRegion = testRegion.IsVisible(testPoint);
}
