LINQ Partition List into Lists of 8 members [duplicate]

Use the following extension method to break the input into subsets

public static class IEnumerableExtensions
{
    public static IEnumerable<List<T>> InSetsOf<T>(this IEnumerable<T> source, int max)
    {
        List<T> toReturn = new List<T>(max);
        foreach(var item in source)
        {
                toReturn.Add(item);
                if (toReturn.Count == max)
                {
                        yield return toReturn;
                        toReturn = new List<T>(max);
                }
        }
        if (toReturn.Any())
        {
                yield return toReturn;
        }
    }
}
