RequiredEnum

RequiredEnum is an open-source analyzer that helps handle all enum values for switch.

Installation

NuGet: dotnet add package requiredenum

Usage

Just add 'Required' prefix for any name of enum in your project and you will get the error when one of cases weren't handle in a switch statement.

var test = (RequiredNumbers) Random.Shared.Next(0, Enum.GetNames(typeof(RequiredNumbers)).Length);
switch (test)
{
    case RequiredNumbers.Zero:
        break;
    case RequiredNumbers.One:
        break;
    default:
        throw new ArgumentOutOfRangeException();
}

internal enum RequiredNumbers
{
    Zero,
    One,
    Two
}

This code will throw the error ('Two' case wasn't handle) and it can't be compiled.
