How to Retrieve a C# Enum's Description from its Integer Value?

Retrieve enum description from value in C#

In C#, enumerations can be decorated using the Description attribute, allowing you to associate a meaningful description with each enumeration member. To retrieve the description of a given enumeration value, you can utilize the GetEnumDescription() method as follows:

<code class="language-csharp">public enum MyEnum
{
    Name1 = 1,
    [Description("Here is another")]
    HereIsAnother = 2,
    [Description("Last one")]
    LastOne = 3
}

public static string GetEnumDescription(Enum value)
{
    FieldInfo fi = value.GetType().GetField(value.ToString());
    DescriptionAttribute[] attributes = fi.GetCustomAttributes(typeof(DescriptionAttribute), false) as DescriptionAttribute[];
    return attributes?.Any() == true ? attributes.First().Description : value.ToString();
}</code>

Suppose you want to retrieve the description of a specific enumeration value, represented as an integer (e.g., 1). You can use a cast to convert this integer to an enumeration value before passing it to the GetEnumDescription() method:

<code class="language-csharp">int value = 1;
string description = GetEnumDescription((MyEnum)value);</code>

By casting an integer to the corresponding enumeration type, you can retrieve the associated description of the corresponding enumeration member.
