.NET (Core and Framework)

MSDN [^]wrote:

An enumeration is a named constant whose underlying type is any integral type except Char. If no underlying type is explicitly declared, Int32 is used. Programming languages typically provide syntax to declare an enumeration that consists of a set of named constants and their values.

Enum provides methods to compare instances of this class, convert the value of an instance to its string representation, convert the string representation of a number to an instance of this class, and create an instance of a specified enumeration and value.

C#
[SerializableAttribute]
[ComVisibleAttribute(true)]
public abstract <big>class</big> Enum : ValueType, IComparable, IFormattable, IConvertible

using System.Runtime.InteropServices;

namespace System
{
    // Summary:
    //     Provides the base class for enumerations.
    [Serializable]
    [ComVisible(true)]
    public abstract <big>class</big> Enum : ValueType, IComparable, IFormattable, IConvertible
    {
        members snipped ...
    }
