Using Bitwise operators on flags

Question

I have four flags

Current = 0x1  
Past = 0x2  
Future = 0x4  
All = 0x7

Say I receive the two flags Past and Future (setFlags(PAST

Answer 1

If you use .NET 4 or later I prefer to do this, cleaner imao:

[Flags]
public enum Time
{
    None = 0
    Current = 1,
    Past = 2,
    Future = 4
}

myProp = Time.Past | Time.Future;

if (myProp.HasFlag(Time.Past))
{
    // Past is set...
}
