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

var someEnumValue = Tag.PrimaryNav | Tag.HomePage;

To test if the enum contains a given value:

if ((someEnumValue & Tag.PrimaryNav) == Tag.PrimaryNav)
{

}
