Question

I got a table (in file) which I split into blocks by spaces.

I need structure like this:

----------------------------- |21|22|23|33|3323| |32|32| |434433|545454|5454| ------------------------------ 

It’s more like each row is its own table. How should I do this?

I tried List<List<string>> matrix = new List<List<string>>(); but I can’t seem to find a way to work with it.

EDIT – can someone tell me what’s wrong with this code???? Matrix[0][0] is same as matrix [1][0].. it seems that same row is added to matrix all the time, but I clear it …

static ArrayList ReadFromFile(string filename)     StreamReader SR;     string S;     string[] S_split;      SR = File.OpenText(filename);     S = SR.ReadLine();      ArrayList myItems = new ArrayList();      List<List<string>> matrix = new List<List<string>>();     List<string> row = new List<string>();      while (S != null)     {         row.Clear();         S_split = S.Split(' ');         for (int i = 1; i < S_split.GetLength(0); i++)         {             row.Add(S_split[i]);             matrix.Add(row);         }                        S = SR.ReadLine();     }     Console.WriteLine(matrix[1][1]);     SR.Close();     return myItems; }

Not sure if I understand this correctly.

        List<List<int>> table = new List<List<int>>();         List<int> row = new List<int>();         row.Add(21);         row.Add(22);         row.Add(23);         row.Add(33); // and so on         table.Add(row);          row = new List<int>();         row.Add(1001);         row.Add(1002);         table.Add(row);          MessageBox.Show(table[0][3].ToString()); 

The program should show a message box with text ’33’.
