Rectangle.IntersectsWith(Rectangle) 方法

定义

命名空间:

System.Drawing

程序集:

System.Drawing.Primitives.dll

Source:

Rectangle.cs

确定此矩形是否与 rect 相交。

public:
 bool IntersectsWith(System::Drawing::Rectangle rect);

public readonly bool IntersectsWith (System.Drawing.Rectangle rect);

member this.IntersectsWith : System.Drawing.Rectangle -> bool

Public Function IntersectsWith (rect As Rectangle) As Boolean

参数

rect

Rectangle

要测试的矩形。

返回

Boolean

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 、 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 );
         }
      }
   }

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
