Question

NormalUser
Custodian
Finance

both Custodian and Finance is a Super

Answer 1

I think this might be a duplicate of How do you pass multiple enum values in C#?

Where the & bitmask can do the trick.

((Role.NormalUser & Role.All) == Role.NormalUser)

Inspecting this closer you will get the following:

0b0 & 0b11 == 0b0

However if you lets say want to check if the SuperUser is in finance you will get the following:

((Role.SuperUser & Role.Finance) == Role.Finance)

This will evaluate to:

0b11 & 0b10 == 0b10
