Convert an array of chars to an array of integers

Question

I have these arrays

char[] array = {'1', '2', '3', '4'};
int[] sequence = new int[array.Length];  

Is there an easy way to assign the numbers in array to sequence?

I tried this

for (int i = 0; i < array.Length; i++)
{
    seqence[i] = Convert.ToInt32(array[i]);
}

But I get the ASCII coding of 1, 2, 3, 4 not the numbers by itself.

Answer 1

using System.Linq;

char[] array = { '1', '2', '3', '4' };
var ints = array.Select(x => int.Parse(x.ToString()));

Answer 2

Just convert the char to a string first:

for (int i = 0; i < array.Length; i++)
{
     sequence[i] = Convert.ToInt32(array[i].ToString());
}

But of course, you could do this all in a single linq query:

char[] array = {'1', '2', '3', '4'};
int[] sequence = array.Select(c => Convert.ToInt32(c.ToString())).ToArray();
