A VarArray (Variant Array) is the most heterogeneous of the ArcObjects arrays. It operates in a similar manner to an Array object, but in addition to storing object references, it can store numeric values, text, dates, booleans, or any data corresponding to a VARIANT as defined in the Microsoft Automation SDK; this is equivalent to the Visual Basic 6 Variant data type.

Supported Platforms

Windows, Solaris, Linux

IXMLSerialize Provides access to members that XML serialize and deserialize an object to/from XML.
