Best way to define error code and error message mapping in .NET

Question

I want to create custom error code and message mapping file. Currently I use Dictionary<int, string> to store them but I think they may have better way to achieve this.

If there is common practice to do this please let me know.

Answer 1

You could define an enum for your error codes that map to a resource file, that way they can be esaly manage, localized, etc.

Answer 2

Maybe rather have a look at using a resource in the project
