Question

I’ve declared an enum type,
assigned a variable to it
and now I am writing it to the console.
So what use does an enum type have in a real world application?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
   class Enum
{
    enum cars
    {
        Toyota, Nissan, Ferrari, Lamborghini
    }
}
class Program
{
    enum cars
    {
        Toyota, Nissan, Ferrari, Lamborghini
    }
    static void Main(string[] args)
    {
        int a = (int)cars.Ferrari;
        Console.WriteLine(a);
    }
}
}

Answer 1

Whenever a procedure accepts a limited set of variables, consider using an enumeration. Enumerations make for clearer and more readable code, particularly when meaningful names are used.

The benefits of using enumerations include:

• Reduces errors caused by transposing or mistyping numbers.

• Makes it easy to change values in the future.

• Makes code easier to read, which means it is less likely that errors
  will creep into it.

• Ensures forward compatibility. With enumerations, your code is less
  likely to fail if in the future someone changes the values
  corresponding to the member names.
