I have an array like this:

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

I would like to convert it in sub arrays like this:

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

Basically I want to group the array in groups of n members

Is there any LINQ function to help me to accomplish this??

I was thinking in the GroupBy or SelectMany but I have not figured out how to do it

Note, I already did this using a foreach statement, but I would like to do it using LINQ

        int[] ar = new int[] {1,2,3,4,5,6};
        var gr = ar
            .Select( (e, i) => new {e, p=i/3})
            .GroupBy( e => e.p )
            .Select( g => g
                .Select(e => e.e)
                .ToArray()
            )
            .ToArray();
