Question

Is there anyway to foreach through a list from the end to the beginning rather than the beginning to then end (preferably without reordering the list).

Answer 1

using System.Linq;

foreach(var item in source.Reverse())
{
    ...
}

Edit: There is one more step if you are dealing specifically with a List<T>. That class defines its own Reverse method whose signature is not the same as the Enumerable.Reverse extension method. In that case, you need to “lift” the variable reference to IEnumerable<T>:

using System.Linq;

foreach(var item in list.AsEnumerable().Reverse())
{
    ...
}
