範例
下列範例示範如何使用 ConnectionStringsSection。
// Create a connection string element and add it to
// the connection strings section.
static ConnectionStrings()
{
// Get the application configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);
// Get the current connection strings count.
int connStrCnt =
ConfigurationManager.ConnectionStrings.Count;
// Create the connection string name.
string csName =
"ConnStr" + connStrCnt.ToString();
// Create a connection string element and
// save it to the configuration file.
// Create a connection string element.
ConnectionStringSettings csSettings =
new ConnectionStringSettings(csName,
"LocalSqlServer: data source=127.0.0.1;Integrated Security=True;" +
"Initial Catalog=aspnetdb", "System.Data.SqlClient");
// Get the connection strings section.
ConnectionStringsSection csSection =
config.ConnectionStrings;
// Add the new element.
csSection.ConnectionStrings.Add(csSettings);
// Save the configuration file.
config.Save(ConfigurationSaveMode.Modified);
}
