How Can I Iterate Through All Enum Values in C#?

Enumerating Enum Values in C#

Looping through all possible values of an enum is a common requirement in C# programming. Here's how you can achieve it:

Using Enum.GetValues Method

The Enum.GetValues method returns an array of all values in the specified enum type. You can use this array to loop through the values using a foreach loop. For example:

public enum Foos
{
    A,
    B,
    C
}

var values = Enum.GetValues(typeof(Foos));

foreach (var value in values)
{
    // Do something with the value
}

Using the Typed Enum.GetValues Method

The Enum.GetValues method also has a typed version that returns an array of the specified enum type. This version is more convenient to use when you know the enum type at compile time. For example:

var values = Enum.GetValues(typeof(Foos)).Cast<Foos>();

Using a Helper Class

To simplify the process of getting enum values, you can create a helper class that provides a generic method for retrieving values:

public static class EnumUtil
{
    public static IEnumerable<T> GetValues<T>()
    {
        return Enum.GetValues(typeof(T)).Cast<T>();
    }
}

Usage:

var values = EnumUtil.GetValues<Foos>();
