EntityDescriptor Class
July 26, 2012
Description of modifications done to entities by operations returned in a DataServiceResponse.
Namespace:
System.Data.Services.Client
Assembly: System.Data.Services.Client (in System.Data.Services.Client.dll)
The EntityDescriptor type exposes the following members.
| Name | Description | |
|---|---|---|
 | EditLink | Gets or sets the URI that modifies the entity. |
| EditStreamUri | Gets or sets the URI that modifies the binary property data of the entity. |
| Entity | Gets the entity that contains the update data. |
| ETag | Gets an eTag value that indicates the state of data targeted for update since the last call to BeginSaveChanges. |
| Identity | Gets or sets the URI that is the identity value of the entity. |
| ParentForInsert | Gets the parent entity that is related to the entity. |
| ParentPropertyForInsert | Gets the name of the property of the entity that is a navigation property and links to the parent entity. |
| ReadStreamUri | Gets or sets the URI that accesses the binary property data of the entity. |
| SelfLink | Gets or sets the URI that is used to return the entity resource. |
| ServerTypeName | Gets or sets the name of the type in the data source to which the entity is mapped. |
| State | When overridden in a derived class, gets the state of the object at the time this instance was constructed. (Inherited from Descriptor.) |
| StreamETag | Gets the eTag for the media resource associated with an entity that is a media link entry. |
The EndSaveChanges 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 BeginSaveChanges was called.
