Question

cmd.CommandText = "select name from Tbl_Shahr_No";
SqlDataReader reader = null;
reader = cmd.ExecuteReader();
reader.Read();

while(reader.HasRows)
{
    ddl.Items.add(reader["name"].tostring());
    reader.read()
}

i wrote this code but problem is that while statement is true all times!
how can i read all of reader information with a while or repeater ring?

Answer 1

The simplest idea is to simply let Read() be the loop condition.

while (reader.Read())
{
     // grab data
}
