Getting the name of the Enumeration Constant having Specified value in C#

Enum.GetName(Type, Object) Method is used to get the name of the constant in the specified enumeration that has the specified value.

Syntax:

public static string GetName (Type enumType, object value);

Parameters:

• enumType: It is an enumeration type.
• value: It is the value of a particular enumerated constant in terms of its underlying type.

Returns: It is a string containing the name of the enumerated constant in enumType whose value is the value or null if no such constant is found.

Exceptions:

• ArgumentNullException: If the enumType or value is null.
• ArgumentException: If the enumType is not an Enum or value is neither of type enumType nor does it have the same underlying type as enumType.

Example:

// C# program to illustrate the
// Enum.GetName(Type, Object) Method
using System;

enum Animals { Dog,
               Cat,
               Cow,
               Monkey };

class GFG {

    // Main Method
    public static void Main(String[] args)
    {

        // using the method
        Console.WriteLine("2nd value is {0}", Enum.GetName(typeof(Animals), 1));
        Console.WriteLine("4th value is {0}", Enum.GetName(typeof(Animals), 3));
    }
}

Output:
