Introduction
[edit | edit source]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
[edit | edit source]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
[edit | edit source]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"
