Rect.Intersect Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Finds the intersection of the rectangle represented by the current Rect and the rectangle represented by the specified Rect, and stores the result as the current Rect.

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


Public Sub Intersect ( _
    rect As Rect _
public void Intersect(
    Rect rect



If no intersection exists, the current Rect becomes Rect.Empty.

Because this method alters the current Rect it acts upon even if there is no intersect, it is often a best practice to retain a copy before calling Intersect in case the intersect is empty or otherwise not a desirable value.
