what are attributes in .NET ?
Santosh Kumar Kotnala
An attribute is a declarative tag that is used to convey information to runtime about the behaviour of programmatic elements such as classes,enumerators and assemblies.
Attributes provide a powerful method of associating metadata, or declarative information, with code (assemblies, types, methods, properties, and so forth). After an attribute is associated with a program entity, the attribute can be queried at run time by using a technique called reflection.
