How do I determine if an Enum value has one or more of the values it's being compared with?

Question

I\'ve got an Enum marked with the [Flags] attribute as follows:

[Flags]
public enum Tag : int
{
    None = 0,
    PrimaryNav = 1,
    HideChildPages = 2,
            


        

Answer 1

You could use Jon Skeet's Unconstrained Melody library:

var someEnumValue = Tag.PrimaryNav | Tag.HideChildPages;
someEnumValue.HasAny(Tag.PrimaryNav | Tag.HomePage); // Returns true
