下列範例示範如何存取 ConnectionStringSettingsCollection。
static void ShowConnectionStrings()
{
// Get the application configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);
// Get the connectionStrings section.
ConnectionStringsSection csSection =
config.ConnectionStrings;
for (int i = 0; i <
ConfigurationManager.ConnectionStrings.Count; i++)
{
ConnectionStringSettings cs =
csSection.ConnectionStrings[i];
Console.WriteLine($" Connection String: \"{cs.ConnectionString}\"");
Console.WriteLine($"#{i}");
Console.WriteLine($" Name: {cs.Name}");
Console.WriteLine($" Provider Name: {cs.ProviderName}");
}
}
