Enumerator or foreach - which one is better

Enumerator or foreach - which one is better

• Robert Horvick MSFT

  That may well be slower than:
  
  for (int i=0; i < list.Count; i++)
  {
  ....
  }
  
  
  as the JIT is able to eliminate some bounds checking.
  
  However, I would use a foreach for the sake of readability (assuming the index isn't required separately). The performance hit - if any - is likely to be completely insignificant.

  Item 11 in Effective C# by Bill Wagner specifies "Prefer foreach loops".
  
  It goes on at some length to justify that suggestion, but it is too long for me to reproduce here. Some of them are noted here:

  I Guest that the fast way is to use a normal for to iterate the List

  List<int> list = new List<int>();

  // Here we add the items to the list

  int length = list.Count;

  for (int i = 0; i < length; i++)

  {

  //Do you code for the list here.

  }
