System_CAPS_pubproperty ETag

Gets an eTag value that indicates the state of data targeted for update since the last call to SaveChanges.

System_CAPS_pubproperty Identity

Gets or sets the URI that is the identity value of the entity.

System_CAPS_pubproperty ParentForInsert

System_CAPS_pubproperty ReadStreamUri

Gets or sets the URI that accesses the binary property data of the entity.

System_CAPS_pubproperty SelfLink

Gets or sets the URI that is used to return the entity resource.

System_CAPS_pubproperty ServerTypeName

Gets or sets the name of the type in the data source to which the entity is mapped.

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 StreamETag

Gets the eTag for the media resource associated with an entity that is a media link entry.

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 changes that were persisted.

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