22.7 Enumerations

C# uses the enum statement along with opening and closing braces to indicate the beginning and end of an enumeration definition. For example:

public enum CheckedState {
// enumeration members 
}

In VB, an enumeration is defined by the Enum... End Enum construct. For example, the VB version of the CheckedState enum declaration is:

Public Enum CheckedState
' enumeration members
End Enum

In both C# and VB, the member listing consists of the name of the enumerated member and its value. These are identical in C# and VB, except that C# adds a comma to separate one member of the enumeration from another, whereas VB requires that they be on separate lines. For example, the full declaration of the CheckedState enumeration in C# is:

public enum CheckedState {
Unchecked = 0, 
Checked = 1,
Indeterminate = 2 
}

The VB equivalent is:

Public Enum CheckedState
Unchecked = 0 
Checked = 1
Indeterminate = 2 
End Enum
