将逗号分隔的值绑定到数据表C＃中

Question

My problem is somewhat same as Mentioned in - How to add comma separated string into datatable in c#?

But in my case the number of columns are not fixed. Where High is the highest value while others are values at different time intervals.

So, I have to show the values till midnight... Like if user chooses 1 pm i have to show from 1 pm to midnight all values.. So what user choose will vary, they can choose 2pm 4 am so on so the number of columns will vary.

Product Name High 15:00 14:45 14:30 14:15 14:00 13:45 13:30... Product1 12 10 10 10 10 10 12 0 n Product2 10 10 0 0 0 0 0 0 n Product3 10 10 10 10 10 10 5 5 n

I am able to bind the data in form of comma separate values but how to bind in datatable I am not understanding..

My comma separated values is somewhat like below from 15:45 to midnight in case if we consider user has choosen 15th hour..

Product1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1|

Product2,9.00,1,1,1,9.00,1,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1|

How about code like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;


namespace ConsoleApplication22
{
    class Program
    {
        static void Main(string[] args)
        {
           string[] inputs = {
                     "Product1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1",
                     "Product2,9.00,1,1,1,9.00,1,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1"
                             };
           List<List<string>> data = new List<List<string>>();
           foreach (string input in inputs)
           {
               List<string> newData = input.Split(new char[] { ',' }).ToList();
               data.Add(newData);
           }


           DataTable dt = new DataTable();
           int maxRows = data.Select(x => x.Count).Max();
           for(int column  = 0; column < data.Count; column++) 
           {
               dt.Columns.Add(data[column][0], typeof(string));
               dt.Columns[column].AllowDBNull = true;
           }
           for (int row = 0; row < maxRows; row++)
           {
               dt.Rows.Add();
           }

           for (int column = 0; column < data.Count; column++)
           {
               for (int row = 0; row < data[column].Count; row++)
               {
                   dt.Rows[row][column] = data[column][row];
               }
           }


        }

    }
