A pretty basic chunk method I use to chunk, or split, lists of items

Chunk list of items.cs

public static IEnumerable<T[]> Chunk<T>( this T[] source, int size )
{
	var acc = new List<T>( size );
	for ( var i = 0; i < source.Length; i++ )
	{
		acc.Add( source[i] );
		if ( acc.Count < size && i < source.Length - 1 )
			continue;
		yield return acc.ToArray();
		acc.Clear();
	}
}
