Property Value

Type: System.Windows.Size
A Size structure that specifies the width and height of the rectangle.
ExceptionCondition

The following example shows how to use code to create a rectangle and add it to the page. The example also illustrates how to find size and coordinate information about the new rectangle and render the information in a TextBox below the rectangle.


// Create a rectangle and add it to the page. Also,
// find size and coordinate information about this
// new rectangle and render information in a TextBox 
// below the rectangle.
private StackPanel createRectExample1()

    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. Set the Location property to an X coordinate of 10 and a
    // Y coordinate of 5. 
    myRectangle.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle.Size = new Size(200, 50);

    RectangleGeometry myRectangleGeometry = new RectangleGeometry();
    myRectangleGeometry.Rect = myRectangle;

    // This path is defined by the rectangle.
    Path myPath = new Path();

    myPath.Stroke = Brushes.Black;
    myPath.StrokeThickness = 1;
    myPath.Data = myRectangleGeometry;
