Question about FileAttributes Enumeration

[Edgardo Rossetto]

Quoting from MSDN docu:

"This enumeration has a FlagsAttribute attribute that allows a bitwise
combination of its member values"

I don't get it, how can I check if FileSystemInfo.Attribute has the
Hidden and System attribute, or maybe only one of those?

Its obnoxiously designed really, although logical. You have to use the
bitwise and operator(&) and a comparison

if ((fsi.Attribute & FileAttributes.Hidden) != 0)
{
//FileAttributes.Hidden is set
}

and so on.
