{
	red = 1,
    green = 2,
    blue = 3,
    white = 4,
    black = 5

}

// How to get the values?

var itemRed = Colors.red;

Console.WriteLine((int)itemRed);  // Using casting to convert to int


// How to get the keys?

var itemX = 4;

Console.WriteLine((Colors)itemX);  // Using casting to convert to Colors
 

// How to convert enums to strings? 

var itemBlue = Colors.blue;

Console.WriteLine(itemBlue.ToString());


// How to convert strings to enums? 

var colorName = "green";

var enumName = (Colors)Enum.Parse(typeof(Colors), colorName);

Console.WriteLine(enumName);       // To see the key
Console.WriteLine((int)enumName);  // To see the value

Example 3: enum c#

Random random = new Random();
