Remarks

ImplementedInterfaces returns a CodeElements collection, each element of type vsCMElementInterface (see vsCMElement) and representing an interface implemented by the code class.

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).
