Edit Question
Title
Body
A new feature in C# / .NET 4.0 is that you can change your enumerable in a foreach without getting the exception. See Paul Jackson's blog entry An Interesting Side-Effect of Concurrency: Removing Items from a Collection While Enumerating for information on this change. What is the best way to do the following? foreach(var item in Enumerable) { foreach(var item2 in item.Enumerable) { item.Add(new item2) } } Usually I use an IList as a cache/buffer until the end of the foreach , but is there better way?
