C# – elegant way of partitioning a list?

by

Here is an extension method that will do what you want:

public static IEnumerable<List<T>> Partition<T>(this IList<T> source, Int32 size)
{
    for (int i = 0; i < (source.Count / size) + (source.Count % size > 0 ? 1 : 0); i++)
        yield return new List<T>(source.Skip(size * i).Take(size));
}

Edit: Here is a much cleaner version of the function:

public static IEnumerable<List<T>> Partition<T>(this IList<T> source, Int32 size)
{
    for (int i = 0; i < Math.Ceiling(source.Count / (Double)size); i++)
        yield return new List<T>(source.Skip(size * i).Take(size));
}
