C# AuthenticationTypes?

Question

I came across the following line in a piece of code that uses Microsoft Active Directory:

const AuthenticationTypes ADS_EDMSERVER_BIND = (AuthenticationTypes)0x8000;

What exactly does this line mean ? Particularly, what is the 0x8000 mean ?

@NikolaiSamteladze If it is 32768, what is its purpose in this case ? — oneCoderToRuleThemAll, Jul 26 '15 at 00:22
You mean what is the purpose of using hexadecimal instead of an integer? — Nikolai Samteladze, Jul 26 '15 at 00:24
Please see my answer. The number just specifies some `AuthenticationTypes` value or may be used as a mask in bit operations (e.g. `|` or `&`). Need to see how `AuthenticationTypes` enumeration looks and how `ADS_EDMSERVER_BIND` to provide more details. — Nikolai Samteladze, Jul 26 '15 at 00:36

0x8000 is just a hexadecimal representation of integer 32768. So this line of code essentially defines a constant of enumerable type AuthenticationTypes with a value of 32768. The number just specifies some AuthenticationTypes value or may be used as a mask in bit operations (e.g. | or &).

Hexadecimal representations are sometimes used to improve readability or show relations to binary values (there is a nice discussion here). The simplest example is constants that are used in masks or with bit operators.
