Converting a string into array of integers

The following is a piece of code I have written

string arrayToConvert = "$78 89 12 78 89 12%";
string s2 = s1.Substring(1, s1.Length - (2));

There are 2 objectives to be achieved

  1. Removing the first and last character
  2. Transferring the string data into array of integers

I am able to remove the first and last character in a string and store it into a new one, no problem. The trouble is when I try to put the data into integer array. I tried using the following syntax to achieve the desired goal.

int[] ia = s1.Split(' ').Select(int.Parse).ToArray();

and

int n;
int[] ia = s1.Split(' ').Select(s => int.TryParse(s, out n) ? n : 0).ToArray();

The output obtained is "4455667788110121" which clearly are not the numbers in the input string. If this question is a duplicate, kindly point me in the right direction. Any help appreciated.

Most likely you are using the wrong strings. Your original string is `arrayToConvert yet you try to clean up some other string, s1. Finally you try to split s1, not the cleaned up s2.

The following line returns an array with the expected values:

var ints= "$78 89 12 78 89 12%"
              .Trim(new[]{'$','%'})
              .Split(' ')
              .Select(int.Parse)
              .ToArray();

I used Trim rather than Substring simply to put everything in a single statement.
