You need to use String.Split Method to split your string with space ‘ ‘ in an array of strings and then convert each element to integer. You can iterate string array using System.Linq in efficient manner

Try changing it to this:

You are not splitting the string using space delimiter.

You cant try with "1 1 3 1 2 2 0 0", because it is trying to parse the spaces between the numbers. If you want your program to work you have to either make your input string like that: "11312200" or you can make a char array or just a single char if you dont have more than one separator where you assign and then .split the string by passing the separator, like that:

You can do this with a simple extension method:

If you don’t want to get an exception you can use this. It returns new int[] <0>when throw an exception.

Given a string str containing numbers separated with “, “. The task is to convert it into an integer array and find the sum of that array.


Recommended: Please try your approach on first, before moving on to the solution.


  • Create an empty array with size as string length and initialize all of the elements of array to zero.
  • Start traversing the string.
  • Check if the character at the current index in the string is a comma(, ). If yes then, increment the index of the array to point to the next element of array.
  • Else, keep traversing the string until a ‘, ‘ operator is found and keep converting the characters to number and store at the current array element.
    To convert characters to number:

Below is the implementation of the above idea:
