is it faster to loop through array or list c# code example

Example 1: c# loop through array

//iterate the array
for (int i = 0; i < arr.Length; i++)
{
  // loop ...
}
// or
foreach (var element in arr)
{
  // loop ...
}

Example 2: c# loop though array

int[] numbers = { 4, 5, 6, 1, 2, 3, -2, -1, 0 };
foreach (int i in numbers)
{
    System.Console.Write("{0} ", i);
}
// Output: 4 5 6 1 2 3 -2 -1 0
