How to Get an Enum's Description from its Integer Value in C#?

Accessing Enum Descriptions from Integer Values in C#

This guide demonstrates how to obtain the descriptive text associated with an enum member using its integer representation in C#. The core functionality relies on a helper method:

Here's a static method, GetEnumDescription, designed to retrieve the description:

<code class="language-csharp">public static string GetEnumDescription(Enum value)
{
    var fi = value.GetType().GetField(value.ToString());
    var attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);
    return attributes != null && attributes.Length > 0 ? attributes[0].Description : value.ToString();
}</code>

This method efficiently extracts the DescriptionAttribute if present; otherwise, it returns the enum member's name.

To use this method with an integer value, simply cast the integer to your enum type:

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

This code snippet casts intValue to MyEnum before passing it to GetEnumDescription, thus retrieving the description corresponding to the enum member with the integer value 1. This approach provides a clean and efficient way to access the descriptive text of enum members using their integer equivalents.
