Hi,
I'm really get confused on this issue. Hope that someone can help me get
clear after this post.
Take the class System.Web.Caching.Cache for example. In the documentation,
there's a property called Item and the description is:
"Gets or sets the cache item at the specified key. In C#, this property is
the indexer for the Cache class."
But when I tried to access this property, using Cache.Item["keyVaule"], the
compiler complains:
'System.Web.Caching.Cache' does not contain a definition for 'Item'
Can someone explain this strange behavior to me ?
Thanks a lot.

Hi,
In these cases where the doc say that the property X is the indexer you
access it without the property name, the compiler knows how to find it,
cause it's the indexer.
you access it using Cache["key"] you do not have to use the .Item
construction.
Hope this help,

So, my question is why the doc shows the Item property ?
Is it correct that the Item property is only for other languages, but not C#
?
