I need to check for a certain version in one of my components. For that reason I just wanted to introduce a public const int on which I could test.

However, I just read in this SO post When, if ever, should we use const? that it’s probably a bad idea to use a const whenever something changes in the future.

What’s the best way to do that? Using a public readonly int? Using an attribute? I can’t use AssemblyVersion or AssemblyFileVersion as those are not in my hand…

Thanks!

    I’d use the const (in fact, I do use it for that). readonly is initialised at run-time, in fact, it can have a different value every time you run the application [1]. Because of that propery, I’d say it is less useful for a version number.

    A version number is (should be?) hard-coded at compile time, which would be a const. Comparison could be a #define in C.

    I reckon that because of this difference, a const doesn’t use data memory, as a readonly does. I have no sources for that though.
