Örnekler

Aşağıdaki örnek, Type bir için türetilmiş bir nesne belirtmek üzere XmlElementAttributeözelliğini kullanır. Örnek, öğesinin XmlElementAttribute üç örneğini de döndüren ArrayListbir alana uygular. Her örnek alanda izin verilen bir tür belirtir.

Açıklamalar

Type Bir alan veya özellik için türetilmiş bir tür belirtmek üzere özelliğini kullanın.

Bir alan veya özellik bir ArrayListdöndürürse, öğesinin XmlElementAttribute birden çok örneğini üyeye uygulayabilirsiniz. Her örnek için özelliğini diziye eklenebilen bir nesne türüne ayarlayın Type .
