ConnectionStrings section in web.config.

Sql Authentication

XML

<connectionStrings>
  <add name="ConnectDBString" connectionString="server=SqlServerName;database=DatabaseName;uid=User;password=Password;" />
</connectionStrings>

To read the connection string into your code, use the ConfigurationSettings class.

string connStr = ConfigurationManager.ConnectionStrings["ConnectDBString"].ConnectionString;

This will be Helpful to u.

First use the Namespaces

using System.Data.SqlClient;
using System.Web.Configuration;

C#

public partial class Default : System.Web.UI.Page
{
    private static readonly string _connString = String.Empty;
    SqlConnection con = new SqlConnection(_connString);

C#

static Default()
    {
  _connString = WebConfigurationManager.ConnectionStrings["DataBaseNameConnectionString"].ConnectionString;
    }

}

and this code in WEB.Config File

XML

<connectionStrings>
  <add name="DataBaseNameConnectionString" connectionString="Data Source=system name or Server name;Initial Catalog=DataBaseName;user id=sa;password=123" providerName="System.Data.SqlClient"" />
</connectionStrings>
