Rect.Intersect 方法

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

查找两个矩形的交集。

重载

Intersect(Rect)	查找当前矩形和指定矩形的交集，并将结果存储为当前矩形。
Intersect(Rect, Rect)	返回指定矩形的交集。

Intersect(Rect)

查找当前矩形和指定矩形的交集，并将结果存储为当前矩形。

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)

参数

rect

Rect

要与当前矩形相交的矩形。

示例

下面的示例演示如何使用 Intersect(Rect) 该方法查找两个矩形的交集，并将结果存储为矩形。

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;
}

注解

如果不存在交集，则当前矩形变为 Rect.Empty。

Intersect(Rect, Rect)

返回指定矩形的交集。

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

参数

rect1

Rect

要比较的第一个矩形。

rect2

Rect

要比较的第二个矩形。

返回

Rect

两个矩形的交集；如果不存在任何交集，则为 Empty。

注解

下面的示例演示如何使用 Intersect(Rect, Rect) 该方法查找两个矩形的交集。

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;
}
