範例

以下程式碼範例是為 Windows Forms 設計的，並需要 PaintEventArgse，這是 Paint 事件處理程序的參數。 程式代碼會執行下列動作：

• 這樣會產生純藍色的刷子。

• 形成一個矩形。

• 建立矩形區域。

• 填滿螢幕上的矩形區域。

public:
   void FillRegionRectangle( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ blueBrush = gcnew SolidBrush( Color::Blue );

      // Create rectangle for region.
      Rectangle fillRect = Rectangle(100,100,200,200);

      // Create region for fill.
      System::Drawing::Region^ fillRegion = gcnew System::Drawing::Region( fillRect );

      // Fill region to screen.
      e->Graphics->FillRegion( blueBrush, fillRegion );
   }

private void FillRegionRectangle(PaintEventArgs e)
{

    // Create solid brush.
    SolidBrush blueBrush = new SolidBrush(Color.Blue);

    // Create rectangle for region.
    Rectangle fillRect = new Rectangle(100, 100, 200, 200);

    // Create region for fill.
    Region fillRegion = new Region(fillRect);

    // Fill region to screen.
    e.Graphics.FillRegion(blueBrush, fillRegion);
}

Private Sub FillRegionRectangle(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim blueBrush As New SolidBrush(Color.Blue)

    ' Create rectangle for region.
    Dim fillRect As New Rectangle(100, 100, 200, 200)

    ' Create region for fill.
    Dim fillRegion As New [Region](fillRect)

    ' Fill region to screen.
    e.Graphics.FillRegion(blueBrush, fillRegion)
End Sub

備註

A Region 由矩形和路徑組成。 若區域未封閉，則從最後一點到第一點再加一段以封閉該區域。
