Remarks

Returns whether the code element is a code type. If it is, then you can query interface or cast it to a CodeType object. This is true when Kind is vsCMElementClass, vsCMElementInterface, vsCMElementDelegate, vsCMElementStruct, or vsCMElementEnum.

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).
