Do you need a description for an enum?
All values in an enum must adhere to the specified type. If you need to specify descriptions for enum items, you can do this in the description of the parameter or property: A nullable enum can be defined as follows: Note that null must be explicitly included in the list of enum values.
How to describe the sort parameter in Enum?

How to get an enum value from an int?
You can use Enum.Parse to get an enum value from the name. You can iterate over all values with Enum.GetNames, and you can just cast an int to an enum to get the enum value from the int value. The latter will throw an ArgumentException if the value is not found, you may want to catch it inside the function and return the default value.
How to search for string in enum in C #?
As mentioned in previous answers, you can cast directly to the underlying datatype (int -> enum type) or parse (string -> enum type). but beware – there is no .TryParse for enums, so you WILL need a try/catch block around the parse to catch failures.
Which is enum has the same calling convention as the underlying type?
enum class byte : unsigned char { }; The new type is an exact copy of the underlying type, and therefore has the same calling convention, which means it can be used across ABIs without any performance penalty. No cast is required when variables of the type are initialized by using direct-list initialization.
When to use enumeration in Visual Studio 2017?
Visual Studio 2017 version 15.3 and later (available with /std:c++17 ): By defining an enum (regular or scoped) with an explicit underlying type and no enumerators, you can in effect introduce a new integral type that has no implicit conversion to any other type.
Are there reusable enums in OpenAPI 3.0?
