Rect.IntersectsWith(Rect) 方法

定義

命名空間:

System.Windows

組件:

WindowsBase.dll

表示指定的矩形是否與目前矩形交集。

public:
 bool IntersectsWith(System::Windows::Rect rect);

public bool IntersectsWith (System.Windows.Rect rect);

member this.IntersectsWith : System.Windows.Rect -> bool

Public Function IntersectsWith (rect As Rect) As Boolean

參數

rect

Rect

要檢查的矩形。

傳回

Boolean

如果指定的矩形與目前矩形交集則為 true，否則為 false。

範例

下列範例示範如何使用 IntersectsWith 方法來判斷兩個矩形是否相交。

private bool intersectsWithExample()
{
    // 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);

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // IntersectsWith method indicates whether the specified rectangle intersects 
    // with this rectangle. doesIntersect returns true because the two rectangles
    // intersect. 
    bool doesIntersect = myRectangle.IntersectsWith(myRectangle2);

    // Returns true.
    return doesIntersect;
}
