示例

下面的代码示例演示如何使用从类派生的 WebControl 自定义 Web 服务器控件来替代 Render 该方法。 它使用 HtmlTextWriter 类编写 <font> 元素。 写入元素的开始标记后，它使用 InnerWriter 属性来写入字符串，并将此字符串 "<br> The time on the server:" 与属性的值 DateTime.Now 连接起来。

   // Write the opening tag of a Font element.
   writer->WriteBeginTag( "font" );
   
   // Write a Color style attribute to the opening tag
   // of the Font element and set its value to red.
   writer->WriteAttribute( "color", "red" );
   
   // Write the closing character for the opening tag of
   // the Font element.
   writer->Write( '>' );
   
   // Use the InnerWriter property to create a TextWriter
   // object that will write the content found between
   // the opening and closing tags of the Font element.
   // Message is a string property of the control that
   // overrides the Render method.
   TextWriter^ innerTextWriter = writer->InnerWriter;
   innerTextWriter->Write( String::Concat( Message, "<br> The time on the server : ", System::DateTime::Now.ToLongTimeString() ) );
   
   // Write the closing tag of the Font element.
   writer->WriteEndTag( "font" );
}

    // Write the opening tag of a Font element.
    writer.WriteBeginTag("font");
    // Write a Color style attribute to the opening tag
    // of the Font element and set its value to red.
    writer.WriteAttribute("color", "red");
    // Write the closing character for the opening tag of
    // the Font element.
    writer.Write('>');

    // Use the InnerWriter property to create a TextWriter
    // object that will write the content found between
    // the opening and closing tags of the Font element.
    // Message is a string property of the control that 
    // overrides the Render method.
    TextWriter innerTextWriter = writer.InnerWriter;
    innerTextWriter.Write(Message + "<br> The time on the server :" + System.DateTime.Now.ToLongTimeString());

    // Write the closing tag of the Font element.
    writer.WriteEndTag("font");
}

        ' Write the opening tag of a Font element.
        writer.WriteBeginTag("font")
        ' Write a Color style attribute to the opening tag
        ' of the Font element and set its value to red.
        writer.WriteAttribute("color", "red")
        ' Write the closing character for the opening tag of
        ' the Font element.
        writer.Write(">")

        ' Use the InnerWriter property to create a TextWriter
        ' object that will write the content found between
        ' the opening and closing tags of the Font element.
        ' Message is a string property of the control that 
        ' overrides the Render method.
        Dim innerTextWriter As TextWriter = writer.InnerWriter
        innerTextWriter.Write((Message + "<br> The time on the server :" & _
           System.DateTime.Now.ToLongTimeString()))

        ' Write the closing tag of the Font element.
        writer.WriteEndTag("font")
    End Sub
End Class

注解

内部标记内容是在标记语言元素的开始标记和结束标记之间找到的文本。

InnerWriter如果该属性设置为TextWriter类的HttpWriter实例的对象，则会指出此事实，并保存单独的引用。
