A.7. Enumerations

A 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 CommandType {
 // Enumeration members 
}

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

Public Enum CommandType
  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 CommandType enumeration in C# is:

public enum CommandType {
 Text = 1, 
 StoredProcedure = 4, 
 TableDirect = 512
}

The VB equivalent is:

Public Enum CommandType
 Text = 1 
 StoredProcedure = 4
 TableDirect = 512
End Enum
