Splitting an array using LINQ

Question

I have a collection uni-dimensional like this:

[1,2,4,5.....n]

I would like to convert that collection in a bi-dimensional collection like

Answer 1

It's not a pure LINQ but it's intended to be used with it:

public static class MyEnumerableExtensions
{
    public static IEnumerable Split(this IEnumerable source, int size)
    {
        if (source == null)
        {
            throw new ArgumentNullException("source can't be null.");
        }

        if (size == 0)
        {
            throw new ArgumentOutOfRangeException("Chunk size can't be 0.");
        }

        List result = new List(size);
        foreach (T x in source)
        {
            result.Add(x);
            if (result.Count == size)
            {
                yield return result.ToArray();
                result = new List(size);
            }
        }
    }
}

It can be used from your code as:

private void Test()
{
    // Here's your original sequence
    IEnumerable seq = new[] { 1, 2, 3, 4, 5, 6 };

    // Here's the result of splitting into chunks of some length 
    // (here's the chunks length equals 3). 
    // You can manipulate with this sequence further, 
    // like filtering or joining e.t.c.
    var splitted = seq.Split(3);
}
