Visual Basic .NET/Enumerations

Introduction An enumeration is a set of related constants defined by a value type. By default, an enumeration is set to integer and sets the first constant to 0 and the second to 1 and so forth. This is so when values have not been declared. Setting Enumerations An enumeration that is set up with values 0, 1 and 2. (Values are set to integer as data type has not been declared): Enum Terms Net30Days Net60Days Net90Days End Enum An enumeration that sets the constants to 30, 60 and 90. Enum TermValues As Short Net30Days = 30 Net60Days = 60 Net90Days = 90 End Enum Using Enumerations To use an enumeration, you have to call up the enumeration collection name first. Then, like looking into the methods of a class, you then declare the enumeration that you want to use. Dim t As Terms = Terms.Net30Days 't = 0 Dim i As Integer = CInt(Terms.Net30Days) 'i = 0 Dim value As Integer = CInt(TermValues.Net60Days) 'value = 60 Dim name As String = TermValues.Net30Days.ToString 'name = "30" fr:Visual Basic .NET/Énumérations
