Namespace:

System.ServiceModel

Assembly:

Source:

DataContractFormatAttribute.cs

Instructs the Windows Communication Foundation (WCF) infrastructure to use the DataContractSerializer.

Examples

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)]
    double Add(double a, double b);

    [OperationContract, DataContractFormat(Style = OperationFormatStyle.Document)]
    double Subtract(double a, double b);
}

<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

<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

Remarks

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.

Constructors

DataContractFormatAttribute()

Initializes a new instance of the DataContractFormatAttribute class.

Properties

Style	Gets or sets the SOAP style of the serialized data.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
