What Is Enum (C#)?

You might wonder, "So, what is an Enum, exactly?" Said, it's a shortened form of the term "enumeration," which means "list." CEnum #'s data type is different from any other list since it allows you to build a group of named items that are all interconnected. Let's imagine you're working on a project that requires you to catalog the various species of pets individuals may own. If you want to specify all the pet types, you may make an Enum and name it "PetType." That's how simple it is, right? Moreover, since each value has a name, it is easy to understand what it represents. Furthermore, Enums are much more effective than strings or integers when representing this kind of data because they require less storage space and are simpler to compare. Nevertheless, that's not all! Underlying values for an Enum can be of any integral type (like int, short, byte, etc.). Nevertheless, that's not all; keep reading! Attributes, which can be attached to each value in an enum, are pieces of metadata. Having the option to assign a display name, description, and even a custom icon to each value is a huge time-saver. Consider the following use case using characteristics in conjunction with an Enum: Now, using some reflection magic, you can extract the attribute values and present them in a lovely UI, allowing you to show off a list of all the available pet types along with descriptions. We know. That's all there is to it; C# Enums are a highly versatile and powerful method to express connected groupings of data. They contain a ton of cool features like underlying values and attributes. Try using Enums the next time you have similar values to manage in a project. This will help you save space in memory and write more readable code.
