Enumerations and Name Qualification
Normally, when referring to a member of an enumeration, you must qualify the member name with the enumeration name. For example, to refer to the Sunday member of your Days enumeration, you would use the following syntax:
You can avoid using fully qualified names by adding an Imports statement to the namespace declarations section of your code, as in the following example:
An Imports statement imports namespace names from referenced projects and assemblies and from within the same project as the module in which the statement appears. Once this statement is added, you can refer to your enumeration members without qualification, as in the following example:
By organizing sets of related constants in enumerations, you can use the same constant names in different contexts. For example, you can use the same names for the weekday constants in the Days and WorkDays enumerations. If you use the Imports statement with your enumerations, you must be careful to avoid ambiguous references. Consider the following example:
Assuming that Monday is a member of both the Days enumeration and the Workdays enumeration, this code generates a compiler error. To avoid ambiguous references when referring to an individual constant, qualify the constant name with its enumeration. The following code refers to the Saturday constants in the Days and WorkDays enumerations.
