Split List into Sublists with LINQ

Question

Is there any way I can separate a List into several separate lists of SomeObject, using the item index as the delimiter of each s

Answer 1

Try the following code.

public static IList> Split(IList source)
{
    return  source
        .Select((x, i) => new { Index = i, Value = x })
        .GroupBy(x => x.Index / 3)
        .Select(x => x.Select(v => v.Value).ToList())
        .ToList();
}

The idea is to first group the elements by indexes. Dividing by three has the effect of grouping them into groups of 3. Then convert each group to a list and the IEnumerable of List to a List of Lists
