使用例

[Visual Basic, C#, C++] HTML の Label 要素が表示された後に、 Control.Render メソッドのオーバーライドで Flush メソッドを呼び出すコード例を次に示します。

   Inherits WebControl
   'The message property.

   'Accessors for the message property.

   Public Overridable Property Message() As [String]

         Return myMessage
      End Get
      Set(ByVal Value As [String])
         myMessage = Value
      End Set
   End Property


   Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)
      'Output the 'label' html tag
      writer.WriteBeginTag("label")
      'Output the space character.
      writer.Write(HtmlTextWriter.SpaceChar)
      'Output the string "style" followed by "=\"".
      writer.Write(("style" + HtmlTextWriter.EqualsDoubleQuoteString))
      'Output the style attribute "font-size".
