byte

I'm working on a legacy system that uses byte arrays for permission levels.
Example:
00 00 00 00 00 00 00 01 means they have "Full Control"
00 00 00 00 00 00 00 02 means they have "Add Control"
00 00 00 00 00 00 00 04 means they have "Delete Control"

So, if a User has "00 00 00 00 00 00 00 07" that means they have all 3 (as far as it has been explained to me).

Now, my question is that I need to know how to get to "0x07" when creating/checking records.
I don't know the syntax for actually combining 0x01, 0x02 and 0x04 so that I come out with 0x07.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
