provided they aren't inside any containers: Panel, Splitters, GroupBoxes, and so on. If they are, then you need to recurse though the container.Controls collection as well in order to find them.

Whether or not you explicitly declare a namespace in a C# source file, the compiler adds a default namespace. This unnamed namespace, sometimes referred to as the global namespace, is present in every file. Any identifier in the global namespace is available for use in a named namespace.
