Type Description

An object which represents the persistent object with the specified value for its key property.


When implementing the IObjectSpace interface in the BaseObjectSpace class's descendant, don't implement the GetObjectByKey method. It's implemented in the BaseObjectSpace class. The BaseObjectSpace.GetObjectByKey(Type type, object key) method returns null, but it is virtual. So, you should override it in your descendant.

To get the key property value, use the IObjectSpace.GetKeyValue method.
