Obtiene o establece el tipo de objeto que se va a incluir.
public:
property Type ^ Type { Type ^ get(); void set(Type ^ value); };
public Type Type { get; set; }
public Type? Type { get; set; }
member this.Type : Type with get, set
Public Property Type As Type
Type del objeto que se va a incluir.
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 .
