Eigenschaftenwert

Ein TextWriter, der den inneren Markupinhalt schreibt.

Hinweise

Der innere Markupinhalt ist der Text zwischen dem Start- und Endtag eines Elements der Markupsprache.

Wenn die InnerWriter-Eigenschaft auf ein TextWriter-Objekt festgelegt ist, das eine Instanz der HttpWriter-Klasse ist, wird dies erfasst und ein separater Verweis gespeichert.

Beispiel

Im folgenden Codebeispiel wird die Verwendung eines benutzerdefinierten Webserversteuerelements veranschaulicht, das von der WebControl-Klasse abgeleitet ist und die Render-Methode überschreibt. Es verwendet die HtmlTextWriter-Klasse, um ein <font>-Element zu schreiben. Nach dem Schreiben des Starttags des Elements wird mithilfe der InnerWriter-Eigenschaft die Zeichenfolge "<br> The time on the server:" geschrieben, die dann mit dem Wert der DateTime.Now-Eigenschaft verkettet wird.

        ' 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 'Render
End Class 'FirstControl 

    // 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.

    TextWriter innerTextWriter = writer.InnerWriter;
    innerTextWriter.Write(Message + "<br> The time on the server :" + System.DateTime.Now.ToLongTimeString());

   // 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

innerTextWriter.Write(get_Message() + "<br> The time on the server :" 
    + System.DateTime.get_Now().ToLongTimeString());

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