using System;
using System.Configuration;
using System.Web.Configuration;
namespace ConfigurationStringSettings
{
class ConfigurationStringSettings
{
static void DisplayConnectionStrings()
{
// Set the path of the config file.
// Make sure that you have a Web site on the
// same server called TestConfig.
string configPath = "/TestConfig";
// Get the Web application configuration object.
Configuration config =
WebConfigurationManager.OpenWebConfiguration(configPath);
// Get the conectionStrings section.
ConnectionStringsSection csSection =
config.ConnectionStrings;
Console.WriteLine("Display configuration strings.");
for (int i = 0; i <
ConfigurationManager.ConnectionStrings.Count; i++)
{
ConnectionStringSettings cs =
csSection.ConnectionStrings[i];
Console.WriteLine(" Connection String: \"{0}\"",
cs.ConnectionString);
Console.WriteLine("#{0}", i);
Console.WriteLine(" Name: {0}", cs.Name);
Console.WriteLine(" Provider Name: {0}",
cs.ProviderName);
