C# || How To Iterate & Get The Values Of An Enum Using C#

The following is a module with functions which demonstrates how to iterate and get the values of an enum using C#.
This function is a generic wrapper for the Enum.GetValues function.
1. Get Values – Basic Enum
The example below demonstrates the use of ‘Utils.Methods.GetEnumValues‘ to get the values of a simple Enum.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
// Get Values - Basic Enum enum Colors { Red, Green, Blue, Yellow } var colors = Utils.Methods.GetEnumValues<Colors>(); foreach (var color in colors) { Console.WriteLine($"Numeric Value: {(int)color}, Name: {color.ToString()}"); } // expected output: /* Numeric Value: 0, Name: Red Numeric Value: 1, Name: Green Numeric Value: 2, Name: Blue Numeric Value: 3, Name: Yellow */ |
2. Get Values – Numbered Enum
The example below demonstrates the use of ‘Utils.Methods.GetEnumValues‘ to get the values of a numbered Enum.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
// Get Values - Numbered Enum public enum Pets { None = 0, Dog = 1, Cat = 2, Rodent = 4, Bird = 8, Fish = 16, Reptile = 32, Other = 64 } var pets = Utils.Methods.GetEnumValues<Pets>(); foreach (var pet in pets) { Console.WriteLine($"Numeric Value: {(int)pet}, Name: {pet.ToString()}"); } // expected output: /* Numeric Value: 0, Name: None Numeric Value: 1, Name: Dog Numeric Value: 2, Name: Cat Numeric Value: 4, Name: Rodent Numeric Value: 8, Name: Bird Numeric Value: 16, Name: Fish Numeric Value: 32, Name: Reptile Numeric Value: 64, Name: Other */ |
