A Type object which is the type of objects to search for.

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.

The following code snippet (auto-collected from DevExpress Examples) contains a reference to the GetObjectByKey(Type, Object) method.


The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
