在表单加载时读取文件并存储在二维数组中

Question

I'm designing a simple Epos system as a project and I need to read my stock values in from a file at the beginning of the application in the form of a collection so I am trying to use a 2d int array but not having much luck.

The format of my txt file looks like this:

15,10,12,19,8

16,9,11,17,10

7,6,17,14,11

8,8,12,13,5

6,7,13,14,4

1,4,15,10,10

6,9,10,14,13

8,7,9,10,11

8,12,10,15,6

9,7,6,13,9

18,8,7,11,5

7,12,10,8,9

12,6,7,9,10

My code is as follows:

private void ReadToFileOpeningStock(int [,] Stock)
    {
        //create an array to hold data from file 
        string[] OneRowOfDataArray;
        const int StockColumns = 13;
        const int StockRows = 5;
        int[,] STOCK_ITEMS = new int[StockColumns, StockRows];

        try
        {
           
            // Declare a StreamReader variable.
            StreamReader inputFile;

            // Open the file and get a StreamReader object.
            inputFile = File.OpenText("Opening StartingStock.txt");

            while (!inputFile.EndOfStream)
            {
                OneRowOfDataArray = inputFile.ReadLine().Split(',');


                for (int i = 0; i < StockColumns; i++)
                {
                    //Here are the inner columns
                    for (int j = 0; j < StockRows; j++)
                    {
                        
                    }
                }
            }

            inputFile.Close();

            
        }

        catch
        {
            MessageBox.Show("Error");
        }

I also have an empty array named Stock declared with the rest of thevariables that I have declared in the method name above.

int[,] Stock ;

How do I assign my text values to an array so that I can use it later in the application?

Sorry if I'm not being clear, I'm new to programming. Any help would be greatly appreciated. Thanks.

Answer 1

I changed it to use file.readallines as it is what I normally use. I've added an extra array to record all the lines, to then be separated with a split into OneRowOfDataArray. I added outputs and the line to set the value to the STOCK_ITEMS. The only other thing I changed is I removed the spaces in between the rows on the txt file

static int[,] STOCK_ITEMS = new int[4, 3];
        static void Main(string[] args)
        {
            //create an array to hold data from file 
            string[] RowsOfData;//contains rows of data
            string[] OneRowOfDataArray;//will contain values seperated by the rows
            const int StockColumns = 13;
            const int StockRows = 5;
            int[,] STOCK_ITEMS = new int[StockColumns, StockRows];

            try
            {
                // Open the file and get a StreamReader object.
                RowsOfData = File.ReadAllLines("Opening StartingStock.txt");//sets all lines and seperates them into ROWSOFDATA array

                

                for (int i = 0; i < StockColumns; i++)
                {
                    OneRowOfDataArray = RowsOfData[i].Split(',');//splits the values in each row seperate
                    Console.WriteLine();//new line when outputting the data
                    //Here are the inner columns
                    for (int j = 0; j < StockRows; j++)
                    {
                        STOCK_ITEMS[i, j] = Int32.Parse(OneRowOfDataArray[j]);//save to correct index in stock items
                        Console.Write("[" + STOCK_ITEMS[i, j] + "]");//output value from the row
                    }
                }


            }

            catch
            {
                MessageBox.Show("Error");
            }
        }
