normally we define connectionstrings under
<connectionStrings> tag in the web.config
file.membership providers use that
connectionstring.what if we needed to use
the connectionstring in asp.net pages?.

without writing connectionstring codes
again in the page we can use the following
codes in pages to access the connectionstring
of web.config file -

1.add first using System.Configuration;

2.then declare following in appropriate section-

public ConnectionStringSettingsCollection _connections
= ConfigurationManager.ConnectionStrings;

public SqlConnection _connection = new SqlConnection();

_connection.ConnectionString =
_connections["ConnectionStringName"].ConnectionString;

3.now initiate connection by the connectionstring -

SqlConnection conn = new MySql.Data.MySqlClient.MySqlConnection
(_connection.ConnectionString);
