I edit your solution. This works for rows and columns.

static void Main(string[] args)
            {
                int[,] S = null;
                int N = 0;
                string line; //to hold one line of file
                string[] token; //to hold each token in line
                char[] separator = { ',' };


                //open file
                try
                {
                    using (StreamReader sr = new StreamReader(@"C:\Users\sb9923\Desktop\ms.txt"))
                    {
                        line = sr.ReadLine();
                        token = line.Split(separator);
                        N = token.Count();
                        S = new int[N, N];
                        for (int i = 0; i < N; i++)
                            S[0, i] = Convert.ToInt32(token[i]);
                        for (int r = 1; r < N; r++)
                        {
                            line = sr.ReadLine();
                            token = line.Split(separator);
                            for (int c = 0; c < N; c++)
                                S[r, c] = Convert.ToInt32(token[c]);
                        }
                        sr.Close();
                    }
                }
                catch (Exception e)
                {
                    Console.WriteLine("The file could not be read:");
                    Console.WriteLine(e.Message);
                }

                int magicValue = GetSum(N * N) / N;

                //Check for magic
                bool isMagic = true;
                for (int counterY = 0; counterY < S.GetLength(1); counterY++)
                {
                    int rowValue = 0;
                    int columnValue = 0;
                    for (int counterX = 0; counterX < S.GetLength(0); counterX++)
                    {
                        rowValue += Convert.ToInt32(S[counterY, counterX]);
                        columnValue += Convert.ToInt32(S[counterX, counterY]);
                    }

                    if (rowValue != magicValue)
                    {
                        isMagic = false;
                        break;
                    }

                    if (columnValue != magicValue)
                    {
                        isMagic = false;
                        break;
                    }

                    rowValue = 0;
                    columnValue = 0;
                }

                if (isMagic)
                {
                    Console.WriteLine("Yeah it is magic! :)");
                }
                else
                {
                    Console.WriteLine("No magic in the air!");
                }
            }


private static int GetSum(int maxValue)
        {
            if (maxValue < 1)
            {
                return 0;
            }

            return maxValue + GetSum(maxValue - 1);
    }

If you have a question go for asking 😉
