Provides a description of modifications done to entities by operations returned in a DataServiceResponse.
Assembly: System.Data.Services.Client (in System.Data.Services.Client.dll)
Thetype exposes the following members.
|Source||A source entity in a link returned by a DataServiceResponse.|
|SourceProperty||The identifier property of the source entity in a link returned by a DataServiceResponse.|
|State||When overridden in a derived class, gets the state of the object at the time this instance was constructed. (Inherited from Descriptor.)|
|Target||The source entity in a link returned by a DataServiceResponse.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects, each of which contains a sequence of EntityDescriptor or instances that represent persisted changes.
For successful operations, the State property of the descriptor is set to unchanged and the new values for insert and update operations are merged according to the merge settings.
For operations with errors, the State of the descriptor will remain the same as they were before SaveChanges was called.
If an error occurred and processing stopped during an operation, the State will remain unchanged.
