XmlSerializerFormatAttribute Class


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

public ref class XmlSerializerFormatAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method, AllowMultiple=false, Inherited=false)]
public sealed class XmlSerializerFormatAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method, AllowMultiple=false, Inherited=false)>]
type XmlSerializerFormatAttribute = class
    inherit Attribute
Public NotInheritable Class XmlSerializerFormatAttribute
Inherits Attribute


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);
<ServiceContract(), XmlSerializerFormat(Style := OperationFormatStyle.Rpc, _
   Use := OperationFormatUse.Encoded)>  _
Public Interface ICalculator
    <OperationContract(), XmlSerializerFormat(Style := OperationFormatStyle.Rpc, _
        Use := OperationFormatUse.Encoded)>  _
    Function Add(ByVal a As Double, ByVal b As Double) As Double 
End Interface


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 Class.

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.



Initializes a new instance of the XmlSerializerFormatAttribute class.



Gets or sets the SOAP style of the XmlSerializer.


Gets or sets a value that indicates that the XmlSerializer should be used for reading and writing faults.


When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)

Gets or sets a value that specifies the format to use.



Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)

Returns the hash code for this instance.

(Inherited from Attribute)

Gets the Type of the current instance.

(Inherited from Object)

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.
