I\'m using the method elementat(Int32) to get a specific element of a query\'s result.
var mds = db.TDP_MissioniDestinazioni.Where(p => p.Mis
Are you happy to fetch all the "earlier" results? If so, either call ToList() to cache them, or AsEnumerable() to fetch them on each call, with the AsEnumerable just being a way to force the compiler to call Enumerable.ElementAt instead of Queryable.ElementAt.
There may be a better way (e.g. using Take or Skip) though - could you give more information about the bigger picture?
You can simply mix Skip and First to do the trick:
mds.Skip(i).First()
