    {

        SqlConnection myConnection = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=student;User ID=sa;Password=123");
        try
        {
            myConnection.Open();

            SqlCommand myCommand = new SqlCommand();
            myCommand.Connection = myConnection;
            myCommand.CommandText = "select name from names";//you can make it select distinct

            SqlDataReader myReader = myCommand.ExecuteReader();
            string toReturn = "";
            while(myReader.Read())
            {
                if (myReader.Read())
                {
                     toReturn += myReader["name"].ToString() + "#";
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        finally
        {
            myConnection.Close();
        }

        return toReturn; //# as delimiter
    }
