Comentarios

Nota:

A partir de .NET Framework 2.0, se recomienda crear XmlWriter instancias mediante el XmlWriter.Create método y la XmlWriterSettings clase para aprovechar las nuevas funcionalidades.

WriteString hace lo siguiente:

  • Los caracteres &, <y > se reemplazan por &amp;, &lt;y &gt;, respectivamente.

  • Los valores de caracteres del intervalo 0x-0x1F (excepto los caracteres de espacio en blanco 0x9, 0xA y 0xD) se reemplazan por entidades de caracteres numéricos (&#0; a través &#0x1Fde ).

  • Si WriteString se llama a en el contexto de un valor de atributo, las comillas dobles y simples se reemplazan por &quot; y &apos; respectivamente.

Por ejemplo, esta cadena test<item>test de entrada se escribe como test&lt;item&gt;test.

Si text es null o String.Empty, este método escribe un nodo de texto sin contenido de datos.
