LINQ objects, how easy and usefull is this!

I try to use new usefull features from .NET 3.0/3.5 more often.

Today I needed to calculate a sum for objects in a List.

Always before I used foreach loops, but in .NET 3.5 I have LINQ. 

I can calculate my result this way:

var anteileSume = stoffList.Distinct().Sum(stoff => stoff.Anteil);

This is just great! :)


Very helpfull list of LINQ samples I found here on MSDN .
