Reading data from a text file and assigning each row into separate arrays using C#.

C#

Suppose I have a text file with data like below, I want to read first row and store the elements in one array. Read the second row and store in second array and so on. I will be making some manipulations on the array later on. Can you help me to do this in C#. (I'm a beginner)

Input text file:

5,7,3,6,9,8,3,5,7
5,6,8,3,4,5
6,4,3,2,65,8,6,3,3,5,7,4
4,5,6,78,9,4,2,5,6

I would also like to check the number of rows. I would be finding out the mean of each row and some other similar calculations on each row. So I would like to loop through the list and carry out for each of the arrays.

This is the code I have been trying around with:

public static void ReadInputFile(string[] args)
        {
            List<float[]> arrays = new List<float[]>();

            int counter = 0;
            string line;

            // Read the file
            System.IO.StreamReader file = new System.IO.StreamReader("Data.txt");
            while ((line = file.ReadLine()) != null)
            {
                // split the line into a string array on , separator
                string[] splitLine = line.ToString().Split(',');

                // if our split isnt null and has a positive length
                if (splitLine != null && splitLine.Length > 0)
                {

                    // create a lineArray the same size as our new string[]
                    float[] lineArray = new float[splitLine.Length];

                    int posCounter = 0;

                    foreach (string splitValue in splitLine)
                    {
                        // loop through each value in the split, try and convert
                        // it into an int and push it into the array
                        try
                        {
                            lineArray[posCounter] = float.Parse(splitValue);
                        }
                        catch { }
                        posCounter++;
                    }

                    // if our lineArray has a positive length then at it to our
                    // list of arrays for processing later.
                    if (lineArray.Length > 0)
                    {
                        arrays.Add(lineArray);
                    }
                }
                counter++;
            }
            int[] size = new int[counter];


            file.Close();

            // Suspend the screen.
            Console.ReadLine();
        }
