C#

24/10/2016 Currency_Name      0.0843  
24/10/2016 Currency_Name      0.7403  
24/10/2016 Currency_Name      3.430

What I have tried:

C#

private static DataTable getCSVData(string csv_file_path)
      {
          String[] values = File.ReadAllText(csv_file_path).Split(',');
          DataTable dt = new DataTable();

          dt.Columns.Add("Date");
          dt.Columns.Add("Currency");
          dt.Columns.Add("Rate");
          //foreach (string i in values)
          //{
          //    DataRow row = dt.NewRow();
          //    row["Date"] = values[32];

          //    dt.Rows.Add(row);
          //}

         for(int i =0;i<=0;i++)
         {
              DataRow row = dt.NewRow();
              row["Date"] = Convert.ToDateTime(values[32]).ToString("dd/MM/yyyy");

Easiest way? Use this: A Fast CSV Reader[^] - it can read directly into a DataTable IIRC, and it saves you a whole load of hassle!
