备注

Variables are grouped into namespaces for disambiguation. The System namespace is created automatically for every package and contains read-only properties. The User namespace contains custom properties that you can add. You can also create a namespace of your choosing to which to add variables. This class inherits from several classes and interfaces, including two from the Visual Studio .NET Framework:
