Enums, Flags, and Bitwise operations [C# / DotNet]
Рет қаралды 2,866
Күн бұрынEnums, flags, and bitwise operations in DotNet with examples using C#. In this video we explain how to setup an enumeration for binary operations (examples include bitwise OR, and bitwise SHIFT), and explain general usage. Not to be confused with IEnumerable!

Must-have additional info from Coda17 on Reddit: If you are using an enumeration as flags you should add the `[Flags]` attribute to the class. Additionally, enums don't have to be integers, there are several other types you can use to store the enum (although, you usually need a special reason to use a different type). Bonus tip: I like to number my flags using bit-shift operator so it's very evident exactly where the numbers are coming from rather than relying on remembering base 2. flagA = 1

Hello sir, can you say a real-world example when flags enums are used in web development? Greetings.

Hi @lav4eee, in web development this is be used frequently in backend, database services, etc. Flags re used anywhere that a true/false is needed, IE 'isAuthenticated', 'isGreen', etc.. but the Bitwise operations would be basically anywhere that combinations of true/false values could represent something of value. I think most real world examples of the bitwise operations are related to hardware and low-level programming, but it definitely can be used in web programming as well depending on your requirements for your app. One thought is a easy/quick way to hash data (using the XOR operator ^), or when manipulating images prior to sending them back to the frontend for example.
