字符串到数组/变量集.NET Bingo

Question

I have a set of thirty numbers in a DB which are all in one cell, separated by spaces. I am evaluating them as such:

    <%# Eval("winning_numbers").ToString().Split(' ')[0]%>
    <%# Eval("winning_numbers").ToString().Split(' ')[1]%>
    <%# Eval("winning_numbers").ToString().Split(' ')[2]%>

And so forth, up to thirty (29). This displays them all in a row. The numbers are random up to 75, like in a bingo game. What I would like to be able to do is to display them in a table, where if the number is between 01 and 15, it displays in the first row, 16-30 = second row, and so forth. Where I'm stuck mentally is that there aren't a finite amount of numbers in each tier - it is totally random. How can I do what I'm looking for?

Answer 1

You are looking for two-dimensional arrays, check this out:

Answer 2

If you have all of them items inside of a list then you can iterate through the list using a for loop

for(int I = 0; I < numlist.Count; I++)
{
     //Inside the for loop we can check the number, and see what column it will fit into.
     if(1 <= I <= 15)
     {
          //The code to put the item into the respective list.
     }
     if(16 <= I <= 30)
     {
          //The code to put the item into the respective list.
     }
     etc...
}
