How Can I Iterate Through Enum Values in C#?

Iterating over enumeration values ​​in C#

Declaring an enumeration in C# allows you to define a set of named constants. Iterating over these values ​​can be useful in a variety of situations.

To iterate over enumeration values, you can utilize the Enum.GetValues method. Consider the following Foos enumeration:

<code class="language-csharp">public enum Foos
{
    A,
    B,
    C
}</code>

Using Enum.GetValues you can retrieve an array of enumeration values ​​like this:

<code class="language-csharp">var values = Enum.GetValues(typeof(Foos));</code>

Alternatively, for the typed version, you can use:

<code class="language-csharp">var values = Enum.GetValues(typeof(Foos)).Cast<Foos>();</code>

To simplify this process, you can implement a helper function, for example:

<code class="language-csharp">public static class EnumUtil
{
    public static IEnumerable<T> GetValues<T>()
    {
        return Enum.GetValues(typeof(T)).Cast<T>();
    }
}</code>

Using this helper function, you can iterate over enumeration values ​​using:

<code class="language-csharp">var values = EnumUtil.GetValues<Foos>();</code>
