Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public bool Contains(
	double x,
	double y
You cannot use methods in XAML.

Type: System.Double

The y-coordinate of the point to check.

Return Value

Type: System.Boolean
true if (x, y) is contained by the rectangle; otherwise, false.

The following example shows how to use the Contains(Double, Double) method to determine if the rectangle contains the point specified by the given x-coordinate and y-coordinate.

private bool rectContainsExample3()
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand  
    // corner of the rectangle. 
    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);

    // Using the Contains method, see if the rectangle contains the specified 
    // point specified by the given X and Y coordinates. doesContain is false  
    // because the X and Y coordinates specify a point outside of myRectangle. 
    bool doesContain = myRectangle.Contains(4, 13);

    return doesContain;
