Poznámky

Pokud při použití atributu Name zadáte hodnotu vlastnosti, musí mít všechny XmlElement objekty XmlNode vložené do pole stejný název prvku a výchozí obor názvů nebo je vyvolán výjimka. Pokud nastavíte Namespace hodnotu vlastnosti, musíte také nastavit Name vlastnost a XmlElement objekty XmlNode musí mít také stejný název a hodnoty oboru názvů. Pokud není zadána žádná Name hodnota, XmlElement můžou mít objekty XmlNode libovolný název prvku.

Při volání Deserialize metody XmlSerializer třídy se v poli shromažďují všechny atributy, které nemají odpovídající člen objektu, který je deserializován. Pokud zadáte Name hodnotu, pole obsahuje pouze elementy XML s tímto názvem. Pokud nezadáte Name hodnotu, matice obsahuje všechny prvky, které nemají v třídě žádný odpovídající člen. Pokud třída obsahuje více než jedno pole, na které je atribut použit, použijte Name vlastnosti a Namespace rozlišovat mezi obsahem polí. Pokud taková třída (s více poli) obsahuje také jedno pole, které nemá žádné odlišné hodnoty vlastnosti nastaveny (tj Name . a Namespace) během deserializace, pole obsahuje všechny prvky XML, které ještě nejsou obsaženy v ostatních polích. Pokud přidáte více než jedno pole, které nemá jinou Name sadu hodnot, Namespace obsahuje poslední pole třídy všechny neznámé prvky, které ještě nejsou obsaženy v ostatních polích, a všechna další pole jsou nastavena na null.

U člena XmlAnyElementAttribute třídy můžete použít více instancí, ale každá instance musí mít jedinečnou Name hodnotu vlastnosti. Nebo pokud je pro každou instanci nastavena stejná Name vlastnost, musí být pro každou instanci nastavena jedinečná Namespace hodnota vlastnosti.
