ChangeInterceptorAttribute Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

The ChangeInterceptorAttribute on a method is used to process updates on the specified entity set name.

Namespace:   System.Data.Services
Assembly:  System.Data.Services (in System.Data.Services.dll)


[AttributeUsageAttribute(AttributeTargets.Method, AllowMultiple = true, 
	Inherited = true)]
public sealed class ChangeInterceptorAttribute : Attribute


Creates a new change interceptor for an entity set specified by the parameter entitySetName.


Gets the name of the entity set to which the interceptor applies.


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


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.)


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.)


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

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

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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

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


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

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

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

Resource-level change authorization and validation is implemented by methods annotated on the ChangeInterceptorAttribute. WCF Data Services provides the infrastructure required for service developers to write per-entity change processing rules and validation.

Entity-level access control and validation can be enforced through query interceptors. For more information, see QueryInterceptorAttribute.

For more information, see the example in the QueryInterceptorAttribute topic.
