Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void Offset(
	Point pos


Type: System.Drawing.Point

Amount to offset the location.

This method adjusts the location of the upper-left corner horizontally by the x-coordinate of the specified point, and vertically by the y-coordinate of the specified point.

The following code example demonstrates the Contains, and Offset methods and the SystemPens class. This example is designed for use with a Windows Form. Paste this code into a form that contains a button named Button1, call DrawFirstRectangle from the form's constructor or Load method, and associate the Button1_Click method with the button's Click event.

Rectangle rectangle1 = new Rectangle(70, 70, 100, 150);

private void DrawFirstRectangle()
        SystemColors.Highlight, FrameStyle.Thick);

private void Button1_Click(object sender, EventArgs e)

    // Get the bounds of the screen.
    Rectangle screenRectangle = Screen.PrimaryScreen.Bounds;

    // Check to see if the rectangle is within the bounds of the screen. 
    if (screenRectangle.Contains(rectangle1))

        // If so, erase the previous rectangle.
            SystemColors.Highlight, FrameStyle.Thick);

        // Call the Offset method to move the rectangle.
        rectangle1.Offset(20, 20);

        // Draw the new, offset rectangle.
            SystemColors.Highlight, FrameStyle.Thick);
