Si especifica un Name valor de propiedad al aplicar el atributo , todos los XmlElement objetos o XmlNode insertados en la matriz deben tener el mismo nombre de elemento y espacio de nombres predeterminado, o se produce una excepción. Si establece el Namespace valor de propiedad, también debe establecer la Name propiedad y los XmlElement objetos o XmlNode también deben tener los mismos valores de nombre y espacio de nombres. Si no se especifica ningún Name valor, los XmlElement objetos o XmlNode pueden tener cualquier nombre de elemento.
Cuando se llama al Deserialize método de la XmlSerializer clase , todos los atributos que no tienen un miembro correspondiente en el objeto que se deserializa se recopilan en la matriz. Si especifica un Name valor, la matriz solo contiene elementos XML con ese nombre. Si no especifica un Name valor, la matriz contiene todos los elementos que no tienen ningún miembro correspondiente en la clase . Si una clase contiene más de un campo al que se aplica el atributo, use las Name propiedades y Namespace para diferenciar entre el contenido de las matrices. Si esta clase (con varios campos) también contiene un campo que no tiene ningún valor de propiedad diferenciador establecido (es decir, Name y Namespace) durante la deserialización, la matriz contiene todos los elementos XML que aún no están incluidos en las demás matrices. Si agrega más de un campo que no tiene un conjunto de valores o Namespace diferenciadoresName, el último campo de la clase contiene todos los elementos desconocidos que aún no están incluidos en las demás matrices y cualquier otro campo se establece nullen .
Puede aplicar varias instancias de a un miembro de XmlAnyElementAttribute clase, pero cada instancia debe tener un valor de propiedad distinto Name . O bien, si se establece la misma Name propiedad para cada instancia, se debe establecer un valor de propiedad distinto Namespace para cada instancia.
