It's not just .Net, flags are used in all the languages. They are just to check the conditions.

Do your mean System.FlagsAttribute, [Flags]?

Flag variable(s) are the notification value, which can be read by its intended user modules, to get the required notification to continue or to stop the process. Conditionally the value of flag is changed by only one process and read by other.
Flags are mostly in boolean, but it also depends upon the scenarios, where it can be even numeric or even in characters.

It's also a possible attribute for enumerators :

C#

[Flags]
public enum MyProperties { None=0, Left=1, Right=2, Center=4, Top=8, Bottom=16, Middle=32, All=64 }

Go here for a complete example (and scroll down to the section labeled Enumeration Types as Bit Flags)

Solution 1

A flag is just a boolean variable used to indicate a particolar condition, for instance

bool done;

done might be false while an operation is still in progress and become true after the operation is completed.
