I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

There are two ways to enumerate an enum in C#:

Using a foreach loop:

using System;

public enum Colors
{
    Red,
    Green,
    Blue
}

public class EnumerateEnum
{
    public static void Main(string[] args)
    {
        // Enumerate the enum using a foreach loop.
        foreach (Colors color in Colors)
        {
            Console.WriteLine("The color is {0}.", color);
        }
    }
}

This code first creates an enum called Colors. The Colors enum has three values: Red, Green, and Blue.

The code then uses a foreach loop to enumerate the Colors enum. The foreach loop will iterate through each value of the Colors enum and print the value to the console.

Using the Enum.GetValues() method:

using System;

public enum Colors
{
    Red,
    Green,
    Blue
}

public class EnumerateEnum
{
    public static void Main(string[] args)
    {
        // Enumerate the enum using the Enum.GetValues() method.
        object[] colors = Enum.GetValues(typeof(Colors));

        // Iterate through the colors array and print each value to the console.
        for (int i = 0; i < colors.Length; i++)
        {
            Colors color = (Colors)colors[i];
            Console.WriteLine("The color is {0}.", color);
        }
    }
}

This code first creates an enum called Colors. The Colors enum has three values: Red, Green, and Blue.

The code then uses the Enum.GetValues() method to get an array of all the values of the Colors enum. The Enum.GetValues() method takes the type of the enum as a parameter.

The code then iterates through the array of values and prints each value to the console.
