public ref class LinkDescriptor sealed : Descriptor


A source entity in a link returned by a DataServiceResponse.


The identifier property of the source entity in a link returned by a DataServiceResponse.


When overridden in a derived class, gets the state of the object at the time this instance was constructed.(Inherited from Descriptor.)


The source entity in a link returned by a DataServiceResponse.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


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 LinkDescriptor instances that represent persisted changes.

For successful operations, the P:System.Data.Services.Client.EntityDescriptor.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 P:System.Data.Services.Client.EntityDescriptor.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 P:System.Data.Services.Client.EntityDescriptor.State will remain unchanged.
