Convert string[][] to int[][]

Question

I am trying to simply convert the type of jagged arrays:

I would like to do it using something like:

int[][] jaggedArray = Array.ConvertAll(jaggedArrayString, int.Parse)

or

int[][] jaggedArray = Array.ConvertAll(jaggedArrayString, delegate(string s) { return int.Parse(s); }

With Linq, I can't do it that way either

int[][] jaggedArray = jaggedArrayString.Select(int.Parse).ToArray();

I didn't find any solution, is there any easy way to do it?

If you want to use LINQ, you need to Select the strings in each sub array, so you need nested Select s:

int[][] result = arr.Select(x => 
                     x.Select(int.Parse).ToArray()
                 ).ToArray();
