Name Description
System_CAPS_pubproperty Source

A source entity in a link returned by a DataServiceResponse.

System_CAPS_pubproperty SourceProperty

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

System_CAPS_pubproperty State

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

System_CAPS_pubproperty Target

The source entity in a link returned by a DataServiceResponse.

Name Description
System_CAPS_pubmethod Equals(Object)

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

System_CAPS_pubmethod GetHashCode()

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

System_CAPS_pubmethod GetType()

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

System_CAPS_pubmethod 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 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.
