Question

I have a custom class “Error” and some pre-created errors (let’s call them A, B and C). Now I’d love to group these pre-created ones under one group (for example, “StockErrors”) and use them kind of like an enum:

private void SomeFunction(Error NewError)
{
    if (NewError == StockErrors.A) DoSomething(); // this is what I need.
}

Any ideas how I could accomplish this? It’s probably something extremely simple…

Thanks in advance!

Answer 1

Make a static class called StockErrors with public static readonly fields of type Error that are initialized to the appropriate values. (You can also use properties)

Depending on your Error class, you may also need to override ==, !=, Equals, and GetHashCode to use value semantics.
