Examples

The following example shows how to add a ConnectionStringSettings object to a ConnectionStringSettingsCollection collection.

// Add a connection string to the connection
// strings section and store it in the
// configuration file.
static void AddConnectionStrings()
{

    // Get the count of the connection strings.
    int connStrCnt =
        ConfigurationManager.ConnectionStrings.Count;

    // Define the string name.
    string csName = "ConnStr" +
        connStrCnt.ToString();

    // Get the configuration file.
    System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);

    // Add the connection string.
    ConnectionStringsSection csSection =
        config.ConnectionStrings;
    csSection.ConnectionStrings.Add(
        new ConnectionStringSettings(csName,
            "LocalSqlServer: data source=127.0.0.1;Integrated Security=True;" +
            "Initial Catalog=aspnetdb", "System.Data.SqlClient"));

    // Save the configuration file.
    config.Save(ConfigurationSaveMode.Modified);

    Console.WriteLine("Connection string added.");
}
