Well that is going to depend on what you are basing the selection of the ID on. You have to have someway to select that first.

Here is the sample code:

C#

var result = from p in db.table1
               join item in db.table2 on p.ID equals item.ID
               select new
               {
                   p.ID,
                   p.FirstName,
                   p.LastName,
               };
foreach (var info in result)
{
   textbox1.Text = info.FirstName + info.LastName
}
