Rect.Intersect 方法

定義

命名空間:

System.Windows

組件:

WindowsBase.dll

尋找兩個矩形的交集。

多載

Intersect(Rect)	尋找目前矩形與所指定矩形的交集，並將結果儲存為目前的矩形。
Intersect(Rect, Rect)	傳回兩個指定之矩形的交集。

Intersect(Rect)

尋找目前矩形與所指定矩形的交集，並將結果儲存為目前的矩形。

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

與目前矩形交集的矩形。

範例

下列範例示範如何使用 Intersect(Rect) 方法來尋找兩個矩形的交集，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

如果沒有交集存在，則目前的矩形會 Rect.Empty 變成 。

Intersect(Rect, Rect)

傳回兩個指定之矩形的交集。

public:
 static System::Windows::Rect Intersect(System::Windows::Rect rect1, System::Windows::Rect rect2);

public static System.Windows.Rect Intersect (System.Windows.Rect rect1, System.Windows.Rect rect2);

static member Intersect : System.Windows.Rect * System.Windows.Rect -> System.Windows.Rect

Public Shared Function Intersect (rect1 As Rect, rect2 As Rect) As Rect

參數

rect1

Rect

要比較的第一個矩形。

rect2

Rect

要比較的第二個矩形。

傳回

Rect

兩個矩形的交集，如果沒有交集則為 Empty。

備註

下列範例示範如何使用 Intersect(Rect, Rect) 方法來尋找兩個矩形的交集。

private Rect intersectExample2()
{
    // 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 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;
}
