Convert String to Int in a Single Line C#

I have a string input like:

1 3 4 1 2

I want to Sum the number into integer. I tried the following code:

using System;
                    
public class Program
{
    public static void Main()
    {
        string input2 = "1 3 4 1 1";
        string value2 = input2.Replace(" ", "+");
        int val = int.Parse(value2);
        
        Console.WriteLine(val);
    }
}

But it is not correct. Does anyone have an idea for this? Thank you.

Solution

  • You can Split input2 with a space character into an array then use system.linq.enumerable.sum()

       string input2 = "1 3 4 1 1";
   var result=  input2.Split(' ').Sum(x=> int.Parse(x));
