Hello,

IL does not have indexers. Infact the c# compiler compiles indexers to
Set_Item and Get_Item (or whatever name I choose via the
IndexerNameAttribute ).
So how does c# (compiler) know that something in a IL Assembly is supposed
to be an indexer ?
And more important, what ways do I have to influence that ?
 
bonk,

I believe that the compiler first looks for the property with the
IndexerNameAttribute. Failing that, I think it will then look for a
property which has the name "Item" (I am pretty shaky on this, but it's the
most prominent thought in my mind right now on the subject).

Hope this helps.
 
Well, that sounds somhow strange to me. Also there is a
PropertyInfo.GetIndexParameters Method.

bonk,

Why would it be strange? And the GetIndexParameters method is only
going to return the parameters for the property if it is an indexer.

Could it be possible that information about indexers are stored somwhere in
the metadata ?
