Type

Type del objeto que se va a incluir.

Ejemplos

En el ejemplo siguiente se define una clase denominada Group, que contiene un campo denominado Employees que devuelve una matriz de Employee objetos. En el ejemplo se deriva la Manager clase de la Employee clase y se aplica XmlIncludeAttribute a la Employee clase . Cuando el ejemplo crea un Group objeto, inserta un Manager objeto en la Employee matriz. Por último, el ejemplo serializa el Group objeto .
