Comentários

Depois que uma mensagem é criada, o corpo da mensagem pode ser lido usando os GetBody métodos na mensagem retornada. O objeto retornado encapsula todos os elementos filho dentro do Body elemento . Como o corpo de uma mensagem é um fluxo, ela só pode ser gravada uma vez ou lida uma vez.

Use a GetBody<T>(XmlObjectSerializer) sobrecarga ao trabalhar com mensagens JSON; a GetBody<T>() sobrecarga não funciona.

public:
generic <typename T>
 T GetBody(System::Runtime::Serialization::XmlObjectSerializer ^ serializer);

public T GetBody<T> (System.Runtime.Serialization.XmlObjectSerializer serializer);

member this.GetBody : System.Runtime.Serialization.XmlObjectSerializer -> 'T

Public Function GetBody(Of T) (serializer As XmlObjectSerializer) As T

public:
generic <typename T>
 T GetBody();

public T GetBody<T> ();

member this.GetBody : unit -> 'T

Public Function GetBody(Of T) () As T
