NameDescription
System_CAPS_pubmethod DataContractFormatAttribute

Initializes a new instance of the DataContractFormatAttribute class.

NameDescription
System_CAPS_pubproperty

Gets or sets the SOAP style of the serialized data.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

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 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);
}
