Intelligent way of removing items from a List while enumerating in C#

Question

I have the classic case of trying to remove an item from a collection while enumerating it in a loop:

List myIntCollection = new List()

I know this post is old, but I thought I'd share what worked for me.

Create a copy of the list for enumerating, and then in the for each loop, you can process on the copied values, and remove/add/whatever with the source list.

private void ProcessAndRemove(IList list)
{
    foreach (var item in list.ToList())
    {
        if (item.DeterminingFactor > 10)
        {
            list.Remove(item);
        }
    }
}
