Assembly: System.Design (in system.design.dll)
The schema objects to return.
Return ValueA collection of schema objects of the specified type.
The GetSchemaItems method returns a collection of all the specified schema objects in the data store.
See the DesignerDataSchemaClass class for the list of schema objects supported by the .NET Framework. Additional schema objects can be added to the DesignerDataSchemaClass class by creating a derived type.
If the data store does not support the requested schema object, the GetSchemaItems method should return a null reference (Nothing in Visual Basic). You can use the SupportsSchemaClass method to determine whether a data store supports the requested schema object before calling the GetSchemaItems method, to avoid returning a null reference (Nothing in Visual Basic) to your application.
If the data store supports the requested object, but does not contain any instances, the GetSchemaItems method should return an empty collection.
