Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
This class represents a collection of ZoomLevels.
