There are ready-made enums

[Flags] public enum UserFlags { guest = 0, // GUEST USER // normal = 1, // NORMAL USER (DEFAULT) // banned = 2, // USER IS BLOCKED // online = 4 // USER IS ONLINE // }

This is how I set the flags:

 user.Flags = UserData.UserFlags.normal; user.SetFlag(UserData.UserFlags.guest); user.SetFlag(UserData.UserFlags.online); public UserFlags Flags { get; internal set; } public void SetFlag(UserFlags flag, bool state = true) { Flags = state ? Flags |= flag : Flags &= ~flag; }

But if I try to display Flags as a test, only Online and Normal returns to the console, but the guest is not taken into account. Why?

The problem is that with the guest flag you are trying to operate with a nonexistent 0th bit. The solution is quite simple - start from the 1st bit:

 [Flags] public enum UserFlags { guest = 1, // GUEST USER // normal = 2, // NORMAL USER (DEFAULT) // banned = 4, // USER IS BLOCKED // online = 8 // USER IS ONLINE // }

Another option is to use a bit shift, so as not to be confused by the values ​​when there are a lot of flags and they become quite large numbers:

 [Flags] public enum UserFlags { guest = 1 << 0, // GUEST USER // normal = 1 << 1, // NORMAL USER (DEFAULT) // banned = 1 << 2, // USER IS BLOCKED // online = 1 << 3 // USER IS ONLINE // }

    ToString() does not handle enum with a value of 0 and does not output to the console
