How Can I Use Friendly Names with Flexible Enum Values in C#?

Tips for using friendly names and flexible enum values ​​in C#

Enumeration types often need to be given more meaningful names to improve code readability and understandability. However, traditional enumeration usage has some limitations in this regard.

For example:

public enum myEnum
{
    ThisNameWorks,
    This Name doesn'tWork,
    Neither.does.this;
}

"ThisNameWorks" is an acceptable enum value, but other values ​​have issues due to containing spaces and special characters. At this time, the "Description" attribute comes in handy.

Description attribute

The

Description attribute allows you to specify a "friendly name" for each enumeration value, which can then be retrieved using an extension method (shown below):

public static string GetDescription(this Enum value)
{
    // 此处省略具体实现
}

Examples of usage

With this extension method you can define enums with user-friendly descriptions:

public enum MyEnum
{
    [Description("Foo 的描述")]
    Foo,
    [Description("Bar 的描述")]
    Bar
}

MyEnum x = MyEnum.Foo;
string description = x.GetDescription();

This approach allows you to create enumerations that have both machine-readable values ​​and human-readable descriptions, improving code maintainability and user experience.
