Hi Saraqueen,

To convert a string into a two-dimensional array, you can first use the Split() method to split the string into Int-type values and store them in a one-dimensional array.

Then read the values in a one-dimensional array and store them in a two-dimensional array.

You can refer to below codes in a C# console demo:

static void Main(string[] args)
        {
            int r = 2, c = 5, n = 20;
            string str = "1,2,3,4,5,6,7,8,9,0";
            string[] Arr = str.Split(',');//Separating strings based on commas
            int[] IArr = new int[n];//Define one-dimensional array
            int[,] CommArr = new int[r, c];//Define two-dimensional array
            for (int i = 0; i < Arr.Length; i++)
            {
                IArr[i] = Convert.ToInt32(Arr[i]);//Store values in one-dimensional array
            }
            for (int i = 0; i < r; i++)
            {
                for (int j = 0; j < c; j++)
                {
                    CommArr[i, j] = IArr[i * c + j];//Store values in two-dimensional array
                    Console.Write(CommArr[i, j] + " ");//display data
                }
                Console.WriteLine("\n");
            }
        }

Best Regard,
