Definition

Namespace:

System.ServiceModel

Assembly:

System.ServiceModel.Primitives.dll

Source:

MessageContractAttribute.cs

Gets or sets the namespace of the message body wrapper element.

C#

public string WrapperNamespace { get; set; }

Property Value

String

The wrapper element namespace.

Examples

The following code example shows the use of the MessageContractAttribute to control the SOAP envelope structure for both the request message and the response message, and the use of both the MessageHeaderAttribute (to create a SOAP header for the response message) and the MessageBodyMemberAttribute (to specify the bodies of both the request and response message). The code example contains an example of each message when sent.
