List to Columns in LINQ

Question

Given an IEnumerable<T> and row count, I would like to convert it to an IEnumerable<IEnumerable<T>> like so:

Input:

Row Count: 3

List: [1,2,3,4,5,6,7]

Output

 
[
 [1,4,7]
 [2,5]
 [3,6]
]

EDIT I would like this to work for any IEnumerable and not depend on T being an Int32.

How can I do this using LINQ?

Answer 1

This will do it:

var list = new List<object> { 1, "two", 3, 4, 5, 6 ,7 };
int count = 3;
var rows = list.Select((item, index) => new { Item = item, Index = index })
            .GroupBy(o => o.Index % count)
            .Select(g => g.Select(o => o.Item));

It should work for any Enumerable
