How to merge array inside another array of it

Question

I have an array which has another array inside of it and I want to merge all of them into one array using linq.

Answer 1

You want to flatten your multidimensional array, use SelectMany:

var mergedValues = values.SelectMany(subArray => subArray)
                         .ToArray();

you can see other examples of flattening different structures here

Answer 2

You are looking for Enumerable.SelectMany:

var flattened = a.SelectMany(row => row).ToArray();
