确定此矩形是否与 rect 相交。
**命名空间:**System.Drawing
**程序集:**System.Drawing（在 system.drawing.dll 中）
语法
声明
Public Function IntersectsWith ( _
rect As Rectangle _
) As Boolean
用法
Dim instance As Rectangle
Dim rect As Rectangle
Dim returnValue As Boolean
returnValue = instance.IntersectsWith(rect)
public bool IntersectsWith (
Rectangle rect
)
public:
bool IntersectsWith (
Rectangle rect
)
public boolean IntersectsWith (
Rectangle rect
)
public function IntersectsWith (
rect : Rectangle
) : boolean
参数
- rect
要测试的矩形。
返回值
如果有重叠，此方法将返回 true；否则将返回 false。
示例
下面的代码示例演示 Intersect)、IsEmpty 和 IntersectsWith 成员。此示例需用于 Windows 窗体。将此代码粘贴到一个窗体中，然后在处理窗体的 Paint 事件时调用此方法，将 e 作为 PaintEventArgs 传递。
Private Sub InstanceRectangleIntersection( _
ByVal e As PaintEventArgs)
Dim rectangle1 As New Rectangle(50, 50, 200, 100)
Dim rectangle2 As New Rectangle(70, 20, 100, 200)
e.Graphics.DrawRectangle(Pens.Black, rectangle1)
e.Graphics.DrawRectangle(Pens.Red, rectangle2)
If (rectangle1.IntersectsWith(rectangle2)) Then
rectangle1.Intersect(rectangle2)
If Not (rectangle1.IsEmpty) Then
e.Graphics.FillRectangle(Brushes.Green, rectangle1)
End If
End If
End Sub
private void InstanceRectangleIntersection(PaintEventArgs e)
{
Rectangle rectangle1 = new Rectangle(50, 50, 200, 100);
Rectangle rectangle2 = new Rectangle(70, 20, 100, 200);
e.Graphics.DrawRectangle(Pens.Black, rectangle1);
e.Graphics.DrawRectangle(Pens.Red, rectangle2);
if (rectangle1.IntersectsWith(rectangle2))
{
rectangle1.Intersect(rectangle2);
if (!rectangle1.IsEmpty)
{
e.Graphics.FillRectangle(Brushes.Green, rectangle1);
}
}
}
private:
void InstanceRectangleIntersection( PaintEventArgs^ e )
{
Rectangle rectangle1 = Rectangle(50,50,200,100);
Rectangle rectangle2 = Rectangle(70,20,100,200);
e->Graphics->DrawRectangle( Pens::Black, rectangle1 );
e->Graphics->DrawRectangle( Pens::Red, rectangle2 );
if ( rectangle1.IntersectsWith( rectangle2 ) )
{
rectangle1.Intersect( rectangle2 );
if ( !rectangle1.IsEmpty )
{
e->Graphics->FillRectangle( Brushes::Green, rectangle1 );
}
}
}
