Question

I want to split and transpose a multiline string from one DataGridView(dgvObs) to separate rows and columns in another DataGridView(dgvSm).
This code works, but – maybe there is a better solution:

object val = dgvObs.Rows[0].Cells[2].Value;
if (val == null) return;

string text = val.ToString();
using (StringReader sr = new StringReader(text))
{
   string line;
   while ((line = sr.ReadLine()) != null)
   {
      string[] divLine = line.Split(',');
      dgvSm.Rows.Add(divLine);
   }
}

Answer 1

Shorter you say? Try this:

var a = dgvObs.Rows[0].Cells[2].Value;

if (a == null) return;

foreach (String s in a.ToString().Split(','))
{
   dgvSm.Rows.Add(s);
}

COMMENT EDIT:

This will read the multiline, split it via regular expressions and then do what my original code did. Simply add the dgvSm.Rows.Add(s); line into the nested foreach statement.

var a = @"I'm a cat, woof.
                    bombs, away";

var result = Regex.Split(a, "\r\n|\r|\n");

foreach (var z in result)
{
   foreach (String sString in z.Split(','))
   {
      var asaa = sString.Trim();
   }
}
