Question

I have a DataTable (id) that has one column (LinkID). The items in the rows for this column are numbers. I am trying to list these numbers in the following format:

1, 2, 30, 494, etc...

How would I get all of the numbers and list them in that way?

Here is what I have tried:

foreach (DataRow row in id.Rows)
{
    foreach (DataColumn column in id.Columns)
    {
        var test = row[0].ToString();
        List<string> ls = new List<string>();
        ls.Add(test);
        MessageBox.Show(ls.ToString());
    }
}

Answer 1

You can the following:

List<string> test = new List<string>();

foreach (DataRow row in id.Rows)
{
   test.Add(row[0].ToString());
}

MessageBox.Show(String.Join(",", test.ToArray()));
