次のコード例は、Windows フォームで使用するように設計されてい PaintEventArgs e ます。これは、イベントハンドラーのパラメーターであるを必要とし Paint ます。The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. コードは、次のアクションを実行します。The code performs the following actions:

  • 黒のペンを作成します。Creates a black pen.

  • 楕円にバインドする四角形を作成します。Creates a rectangle to bound an ellipse.

  • 開始 (45 °) とスイープ (270 °) の角度を定義します。Defines the start (45 degrees) and sweep (270 degrees) angles.
