how to do this using linq?

Question

hello,

please help me to figure out how to replace the loop below with a linq expression:

using System.Web.UI.WebControls;
...
Table table = ...;
BulletedList list = new BulletedList();

foreach (TableRow r in table.Rows)
{
    list.Items.Add(new ListItem(r.ToString()));
}

this is a contrived example, in reality i am not going to convert rows to strings of course.

i am asking how to use BulletedList.AddRange and supply it an array of items created from table using a linq statement.

thanks! konstantin

Answer 2

how about

list.Items.AddRange(table.Rows.Select(r => new ListItem(r.ToString())));

Answer 3

Consider using AddRange() with an array of new ListItems. You'll have to .Cast() to get an IEnumerable of TableRow.

  list.Items.AddRange(
         table.Rows.Cast<TableRow>()
                   .Select(x => new ListItem(x.ToString()))
                   .ToArray()
   );
