is my c# code to do file reading with the display too:

public void populate_grid_by_file()
        {
            int counter = 0;
            string line;

            // Read the file and display it line by line.
            System.IO.StreamReader file =
               new System.IO.StreamReader("data.txt");
            for (int i = 0; i < Sodoku_Gri.GetLength(0); i++)
            {
                while ((line = file.ReadLine()) != null)
                {
                    for (int j = 0; j < Sodoku_Gri.GetLength(1); j++)
                    {
                        Sodoku_Gri[i,j] = line[j];
                        Console.Write(line[j].ToString());

                    }
                    Console.WriteLine(line);
                    counter++;
                }
            }
            file.Close();
            // Suspend the screen.
            Console.ReadLine();
        }   

but when i display my array with the file reading above it is like:

1--2--3--1--2--3--    
3-4-4-5--3-4-4-5--    
-7-3-4----7-3-4---    
7--5--3-67--5--3-6    
--7---4----7---4--    
3-2--4-5-3-2--4-5-    
------3--------3--    
2-6--7---2-6--7---    
4---4--3-4---4--3-

cnt understand why duplication! help!

When i debugged i found that there was a problem in the line:

Console.Write(line[j].ToString());

it means that automatically elements are not being loaded into the array here:

Sodoku_Gri[i,j] = line[j];

Kindly help me with this!

Answer 1

You display the line once, character by character here:

    Console.Write(line[j].ToString());

And then the full line all at once here:

     Console.WriteLine(line);
