Remarques

Les SoapFormatter classes et BinaryFormatter implémentent l’interface IRemotingFormatter pour prendre en charge les appels de procédure distante (RPC) et l’interface IFormatter (héritée par ) pour prendre en charge la IRemotingFormattersérialisation d’un graphique d’objets. La SoapFormatter classe prend également en charge les RPC avec ISoapMessage des objets, sans utiliser la IRemotingFormatter fonctionnalité .

Pendant les RPC, l’interface IRemotingFormatter permet de spécifier deux graphiques d’objets distincts : le graphe des objets à sérialiser et un graphe supplémentaire qui contient un tableau d’objets d’en-tête qui transmettent des informations sur l’appel de fonction distante (par exemple, l’ID de transaction ou une signature de méthode). Pour une sérialisation correcte, l’objet racine du premier graphique doit être un objet qui implémente l’interface IMethodCallMessage ou l’interface IMethodReturnMessage .

Pendant la désérialisation d’un RPC, un HeaderHandler délégué est spécifié à la Deserialize méthode du formateur. L’infrastructure de communication à distance utilise le HeaderHandler délégué pour produire un objet qui prend en charge l’interface ISerializable . Cet objet contient les informations stockées dans les en-têtes et devient la racine du graphique retourné par le désérialiseur.

Peut SoapFormatter également gérer les RPC générés avec des objets qui implémentent l’interface ISoapMessage . Pour créer un RPC sans utiliser la IRemotingFormatter fonctionnalité, placez un objet qui prend en charge l’interface ISoapMessage à la racine d’un graphique en cours de sérialisation. Pour désérialiser un RPC créé de cette manière, la TopObject propriété doit être définie sur un autre objet qui prend en charge l’interface ISoapMessage et contient les informations d’appel à distance pertinentes.

Les objets TimeSpan sont sérialisés selon la norme ISO 8601 : 1998 section 5.5.3.2.1 « Alternative ».
