The SendMessageContent type exposes the following members.

Public methodSendMessageContentInitializes a new instance of the SendMessageContent class.
Public methodSendMessageContent(InArgument)Initializes a new instance of the SendMessageContent class with the specified data to send.
Public methodSendMessageContent(InArgument, Type)Initializes a new instance of the SendMessageContent class with the specified message and message type.

Public propertyDeclaredMessageTypeGets or sets the declared message type.
Public propertyMessageGets or sets the data to send.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodShouldSerializeDeclaredMessageTypeGets a value that indicates whether the DeclaredMessateType property should be XAML-serialized.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

When using this class, messages serialized on the wire are unwrapped, unless the data is a message contract type or of type [System.ServiceModel.Channels.Message].

The following example shows how to use a SendMessageContent instance with a Send activity.

Variable<PurchaseOrder> po = new Variable<PurchaseOrder>();
Variable<Customer> customer = new Variable<Customer>();

Endpoint clientEndpoint = new Endpoint
    Binding = Constants.Binding,
    AddressUri = new Uri(Constants.ServiceAddress)

Send submitPO = new Send
    Endpoint = clientEndpoint,
    ServiceContractName = Constants.POContractName,
    OperationName = Constants.SubmitPOName,
    Content = new SendMessageContent(new InArgument<PurchaseOrder>(po))
