确定此矩形是否与 rect 相交。
public:
bool IntersectsWith(System::Drawing::Rectangle rect);C#
public readonly bool IntersectsWith (System.Drawing.Rectangle rect);C#
public bool IntersectsWith (System.Drawing.Rectangle rect);member this.IntersectsWith : System.Drawing.Rectangle -> boolPublic Function IntersectsWith (rect As Rectangle) As Boolean- rect
- Rectangle
要测试的矩形。
如果有重叠，此方法将返回 true；否则将返回 false。
下面的代码示例演示 、 IntersectIsEmpty 和 IntersectsWith 成员。 此示例应与 Windows 窗体一起使用。 将此代码粘贴到窗体中，并在处理窗体的 Paint 事件时调用此方法，作为 ePaintEventArgs传递。
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 );
}
}
}
C#
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 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
