            ProtectedConfigurationProviderCollection
                providers = ProtectedConfiguration.Providers;

            IEnumerator pEnum =
                providers.GetEnumerator();

            foreach (ProtectedConfigurationProvider provider in
                providers)

            string protectedSectionName =
                ProtectedConfiguration.ProtectedDataSectionName;
            Console.WriteLine(
                "Protected section name: {0}",
                 protectedSectionName);

            // Get the providers' collection.
            GetProviders();

注解

类 ProtectedConfiguration 允许你获取有关可用于保护敏感配置数据的提供程序的信息。 通常使用标准提供程序，但也可以通过从 ProtectedConfigurationProvider 类派生来创建自定义提供程序。

有关受保护配置的详细信息，请参阅 使用受保护的配置加密配置信息。

字段

DataProtectionProviderName	数据保护提供程序的名称。
ProtectedDataSectionName	受保护的数据节的名称。
RsaProviderName	RSA 提供程序的名称。

属性

DefaultProvider	获取默认受保护配置提供程序的名称。
Providers	获取安装的受保护配置提供程序的集合。
