Ejemplos

En el ejemplo siguiente se usa el FromTypes método para devolver una matriz de XmlSerializer objetos.The following example uses the FromTypes method to return an array of XmlSerializer objects. El código incluye tres definiciones de clase que se usan para crear una matriz de Type objetos.The code includes three class definitions that are each used to create an array of Type objects.

Comentarios

El FromTypes método permite crear de forma eficaz una matriz de XmlSerializer objetos para procesar una matriz de Type objetos.The FromTypes method allows you to efficiently create an array of XmlSerializer objects for processing an array of Type objects. Sin embargo, se recomienda que los llamadores almacenen en memoria caché los serializadores devueltos cuando haya llamadas repetidas a este método.However, it is recommended for callers to cache the returned serializers when there are repeated calls to this method.
