Could someone please tell me if the code below that I wrote is alright, or if not right, how to put it right?
I have been searching the Net endlessly - but in vain - for an appropriate example.
Many thanks in advance,
Adrian.
using System;
using System.Collections.Generic;
using System.Data;
using System.Text;
using System.Data.Sql;
using System.Data.SqlClient;
using System.IO;
namespace FilesAndDatabase
{
public sealed class CustomerWrite
{
string name;
string company;
string street;
string pobox;
string city;
string telephone;
string email;
string customer_key;
//public CustomerWrite(string name, string company, string street, string pobox, string city, string telephone, string email, string customer_key)
public CustomerWrite()
{
this.name = "1";// 0 name;
this.company ="2";// 1 company;
this.street="3";//2 street;
this.pobox = "4";// 3 pobox;
this.city ="5";//4 city;
this.telephone ="6";//5 telephone;
this.email="7";//6 email;
this.customer_key="abc";//7 customer_key;
try
{
using(SqlConnection my_connection = new SqlConnection (@"Data Source=.\SQLExpress;Integrated Security=true;AttachDbFilename=C:\NewDatabase\NewTest.mdf;User Instance=true;"))
{
my_connection.Open();
using (SqlDataAdapter my_adapter = new SqlDataAdapter("SELECT * From Customers2", my_connection))
{
using (DataSet my_dataset = new DataSet())
{
using (SqlCommandBuilder bldr = new SqlCommandBuilder(my_adapter))
{
my_adapter.Fill(my_dataset, "Cusomers2");
DataTable my_table = my_dataset.Tables[0];
DataRow dr = my_table.NewRow();
dr[0]= name;
dr[1]= company;
dr[2]= street;
dr[3]= pobox;
dr[4]= city;
dr[5]= telephone;
dr[6]= email;
dr[7]= customer_key.PadRight(20,' ');
my_table.Rows.Add(dr);
my_adapter.Update(my_dataset, "Customers2");
my_table.AcceptChanges();
}
}
}
my_connection.Close();
}
}
catch (Exception x)
{
new Warning("Writing to Customers\r\n" + x.Message);
}
}
}

| Personally, I'd either invoke a stored procedure to do this or just generate an insert statement, but then I am a bit old-school. |

Thank you for your comment. I understand that there are more than one way data can be added to a table in a database. I have no experience with database programming and would like to learn step by step. I would first like to be able to go the data adapter and the insert way, and then to know which way is the best in which circumstances. First I need to know how to code them correctly. (I believe I know how to go the insert way.) So hopefully someone will give give me feedback - correct the code I posted where necessary and can give me some idea which way is the best given which parameters.
