using System.Configuration;
using System.Security.Permissions;

namespace Samples.AspNet

    // Shows how to use the ProviderSettings.

    {

        [PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
        private static void GetProviderSettings()
        {
            // Get the application configuration file.
            System.Configuration.Configuration config =
                    ConfigurationManager.OpenExeConfiguration(
                    ConfigurationUserLevel.None);

            ProtectedConfigurationSection pSection =
                config.GetSection("configProtectedData")
                as ProtectedConfigurationSection;

            ProviderSettingsCollection providerSettings =
              pSection.Providers;

            foreach (ProviderSettings pSettings in
                providerSettings)
            {


                Console.WriteLine(

                    pSettings.Name);

                IEnumerator pEnum =
                    parameters.GetEnumerator();

                int i = 0;
                while (pEnum.MoveNext())

                }
            }

        static void Main(string[] args)
        {

            GetProviderSettings();
        }
    }

下面是上述示例使用的配置文件的摘录。

<?xml version="1.0" encoding="utf-8" ?>  
<configuration>  

  <configProtectedData>  

    <providers>  
      <clear />  
      <add  
         name="TripleDESProtectedConfigurationProvider"   
         type="Samples.Aspnet.TripleDESProtectedConfigurationProvider, protectedconfigurationproviderlib, Version=1.0.0.0, Culture=neutral,   
PublicKeyToken=79e01ae0f5cfc66f, processorArchitecture=MSIL" />  

    </providers>  

  </configProtectedData>  

</configuration>  

注解

ASP.NET 使用提供程序来执行功能所需的特定服务。 例如，成员资格功能使用提供程序来协调数据库中成员资格数据的持久性。

在配置文件中，单个提供程序将添加到 providers 特定功能节内的元素中。

类 ProviderSettings 表示添加到配置节中的 providers 元素的特定设置组。 通常， 指令指定的 add 配置属性包括名称、类型和其他属性。
