How to Retrieve Enum Descriptions from Integer Values in C#?

Retrieve enumeration description from value in C#

Problem Statement:

Consider an enumeration whose members are assigned the Description property:

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

Goal: Get the description of the association from the given enumeration value (e.g., for value 2, get "Here is another").

Proposed solution:

Use the GetEnumDescription() method:

<code class="language-c#">public static string GetEnumDescription(Enum value)
{
    // ... (与问题陈述中提供的代码相同)
}</code>

Retrieve description from integer value:

To get a description from an integer value representing an enumeration, cast the value to the corresponding enumeration type:

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

Explanation:

In C#, enumerations essentially use integers as their underlying data type. By casting an integer value to an enumeration type, you actually convert it to the corresponding enumeration value, allowing you to pass it to the GetEnumDescription() method and retrieve the assigned description.
