首先添加引用:
using System.Web.Configuration;
加密操作如下:
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:
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();
}
}
實(shí)踐:
加密前的配置文件:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="name" value="shy520" />
<add key="address" value="cnblogs" />
</appSettings>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
加密后的配置文件:
<?xml version="1.0"?>
<configuration>
<appSettings configProtectionProvider="DataProtectionConfigurationProvider">
<EncryptedData>
<CipherData>
<CipherValue>

if (appSettings.SectionInformation.IsProtected)
{
appSettings.SectionInformation.UnprotectSection();

else

appSettings.SectionInformation.ProtectSection(

//保存配置信息
