DataContractFormatAttribute Class
Assembly: System.ServiceModel (in system.servicemodel.dll)
'Declaration <AttributeUsageAttribute(AttributeTargets.Class Or AttributeTargets.Method Or AttributeTargets.Interface, Inherited:=False, AllowMultiple:=False)> _ Public NotInheritable Class DataContractFormatAttribute Inherits Attribute 'Usage Dim instance As DataContractFormatAttribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Method|AttributeTargets.Interface, Inherited=false, AllowMultiple=false) */ public final class DataContractFormatAttribute extends Attribute

Not applicable.
This attribute is similar to the XmlSerializerFormatAttribute attribute. Both attributes can be applied to either a method or a class.
A method can have either of the two attributes applied, but not both. Any operation that has neither applied will use the attribute applied to the containing class. If the containing class does not have either attribute applied, the DataContractSerializer is used.
Applying the attribute also causes a DataContractSerializerOperationBehavior to be created at run time. The behavior allows customization at run time of the serializer behavior.
The following example applies the DataContractFormatAttribute and sets the Style property to Rpc. The RPC style is described in the Web Service Description Language specification (WSDL).
<ServiceContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)> _ Interface ICalculator <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)> _ Function Add(ByVal a As Double, ByVal b As Double) As Double <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Document)> _ Function Subtract(ByVal a As Double, ByVal b As Double) As Double End Interface
