首先添加引用: using System.Web.Configuration;

加密操作如下:

以下为引用的内容： private void ProtectSection(string sectionName, string provider)     {         Configuration config =             WebConfigurationManager.                 OpenWebConfiguration(Request.ApplicationPath);         ConfigurationSection section = config.GetSection(sectionName);         if (section != null && !section.SectionInformation.IsProtected)         {             section.SectionInformation.ProtectSection(provider);             config.Save();         }     }

解密操作如下:

以下为引用的内容：  private void UnProtectSection(string sectionName)     {         Configuration config =             WebConfigurationManager.                 OpenWebConfiguration(Request.ApplicationPath);         ConfigurationSection section = config.GetSection(sectionName);         if (section != null && section.SectionInformation.IsProtected)         {             section.SectionInformation.UnprotectSection();             config.Save();         }     }

实践:

加密前的配置文件:
