How i count summary of numbers in a text file?

Question

I did this code, but it doesnt give summary. Still I can get numbers of each row, but not summary...

using System;
using System.IO;
namespace Progaram
{
    class Count
    {
        static void Main()
        {

            using (StreamReader sr = new StreamReader("file.txt"))
            {

                string[] numbers = File.ReadAllLines("file.txt");


                int summary = 0;

                for (int i = 0; i < numbers.Length; i++)
                {

                    summary += numbers[i];

                    //Console.WriteLine(numbers[i]);
                }

                Console.WriteLine(summary);

                sr.ReadLine();
            }
        }
    }
}

Your current solution will not compile.
You'll receive the following compilation error:

Cannot convert type 'string' to 'int'.

You'll want to convert the parsed string into an int.

Also, you're using a StreamReader, and reading a single line after reading in all lines. You don't need the StreamReader in this case.

using System;
using System.IO;

namespace Progaram
{
    class Count
    {
        static void Main()
        {
            string[] numbers = File.ReadAllLines("file.txt");

            int summary = 0;

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

            Console.WriteLine(summary);    
        }
    }
}
