Question

I have a list of array of string: List<string[]> myList;

Is there any way to get an array of strings with all the elements string[0]?
Like List myList to string[] where elements are myList[string[0]]

I suppose it´s something like var result = from x in myList .Take(0) select x

And question 2)
is there any way to convert a string[] to string[1,] without a for loop?
Now I do:

for (int i = 0; i < arr.Length; i++)
      range[0, i] = arr[i];

I need “this syntax” because I´m exporting columns to excel. And I need an object[,] to do a range.set_Value(Type, object[,]).

Answer 1

string[] result = myList.Select(arr => arr.FirstOrDefault()).ToArray();

Is that what you’re looking for?

Take(n) only returns an enumerable with at most n elements, so that’s obviously wrong.
