EntityDescriptor Class

Definition

Description of modifications done to entities by operations returned in a DataServiceResponse.

public sealed class EntityDescriptor : System.Data.Services.Client.Descriptor
type EntityDescriptor = class
    inherit Descriptor
Public NotInheritable Class EntityDescriptor
Inherits Descriptor
Inheritance

Remarks

The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects each of which contains a sequence of EntityDescriptor or LinkDescriptor instances that represent changes that were persisted.

For successful operations, the State property of the descriptor will be set to unchanged and the new values for insert and update operations will be merged according to the merge settings.

For operations with errors, the State of the descriptor will remain the same as it was before SaveChanges was called.

If an error occurred and processing stopped during an operation, the State will remain unchanged.
