asp.net Syntax [] instead of ()

Can some one explain why brackets are used instead of () in the single line of code below (c# codeBehind ASP.NET), and provide the technical document reference for this syntax

string cssFile = Request.Cookies["InquiryId"].Value;

Because Cookies is some kind of dictionary. Or more general: It defines an indexer property. Therefor the [] have to be used. () are used for a method call, which is just something different.

its a c# rather than VB.Net convention for accessing an array, nothing to do with asp.net really, rather the language choice for the code behind

You may take a look at indexed properties. That's what is defined for the Cookies property.

the [] syntax that you are looking at is called the Indexers(msdn link).
