名稱 Description

尋找當前矩形與指定矩形的交點，並將結果儲存為當前矩形。
Intersect(Rect, Rect)

回傳指定矩形的交點。

Intersect(Rect)

尋找當前矩形與指定矩形的交點，並將結果儲存為當前矩形。

public:
 void Intersect(System::Windows::Rect rect);
public void Intersect(System.Windows.Rect rect);
member this.Intersect : System.Windows.Rect -> unit
Public Sub Intersect (rect As Rect)

參數

rect
Rect

矩形與當前矩形相交。

範例

以下範例說明如何使用此 Intersect(Rect) 方法尋找兩個矩形的交點，並將結果儲存為矩形。

private Rect intersectExample1()
{
    // 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);

    // Intersect method finds the intersection between the current rectangle and the 
    // specified rectangle, and stores the result as the current rectangle. If no 
    // intersection exists, the current rectangle becomes the Empty rectangle. 
    // myRectangle now has a size of 190,45 and location of 10,5. 
    myRectangle.Intersect(myRectangle2);

    // myRectangle has been changed into the intersection area between the old myRectangle
    // and myRectangle2 (new size of 190,45 and new location of 10,5).
    return myRectangle;
}

備註

若不存在交集，則當前矩形變為 Rect.Empty。

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

    // The Location property specifies the coordinates of the upper left-hand

    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // Intersect method finds the intersection between the specified rectangles and 
    // returns the result as a Rect. If there is no intersection then the Empty Rect 
    // is returned. resultRectangle has a size of 190,45 and location of 10,5. 
    Rect resultRectangle = Rect.Intersect(myRectangle, myRectangle2);

    return resultRectangle;
}
