Question

I want to work with data that I get from a SQL Server database directly in my ASP.NET code behind page. I have the connection string, should I use DataSet for accessing the data?

I want to work and customize data and then show it on an ASP.NET page in XML format (use it for xmlhttprequest answer).

Sample code would be greatly appreciated!

 SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=user_city;Integrated Security=True");
 con.Open();
 SqlCommand my_command = new SqlCommand("select * from city_buildings where user_id=1",con);

There is many choices to get data from database. You wrote some code to directly retrieve data from database. You can see complete sample from MSDN: http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.aspx

There is also other methods: Entity Framework, NHibernate and etc.
