Once you start using Linq in .NET you never go back... Even simple tasks as looping a list of items you still use Linq. But what happens when you actually need the index variable you get for free when using for-loop? Assume a list of objects: var values = new List<int>() { 2, 3, 4, 0x100, 74, 0xFFFF, 0x0F0F }; To iterate the list and having an index do the following: values.Select((x, i) => new { item = x, index = i }) .ToList() .ForEach(obj => { int value = obj.item; int valueIndex = obj.index; }); See also my answer on Stack Overflow .
