XmlSerializerFormatAttribute Class

Instructs the Windows Communication Foundation (WCF) infrastructure to use the XmlSerializer instead of the XmlObjectSerializer.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Method|AttributeTargets.Interface, Inherited = false, 
	AllowMultiple = false)]
public sealed class XmlSerializerFormatAttribute : Attribute

This attribute is similar to the DataContractFormatAttribute attribute. Both attributes can be applied to a method, class, or interface.

For more information about the XmlSerializer, see Using the XmlSerializer.

A method can have either of the two attributes applied, but not both. Any operation that has neither applied uses 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 XmlSerializerOperationBehavior to be created at runtime. The behavior allows customization at runtime of the serializer behavior.

The following example applies the XmlSerializerFormatAttribute to an interface.

[ServiceContract, XmlSerializerFormat(Style = OperationFormatStyle.Rpc, 
    Use = OperationFormatUse.Encoded)]
public interface ICalculator
    [OperationContract, XmlSerializerFormat(Style = OperationFormatStyle.Rpc, 
        Use = OperationFormatUse.Encoded)]
    double Add(double a, double b);


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
