这篇文章主要介绍了C#加密app.config中连接字符串的方法,涉及C#配置文件加密的相关实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#加密app.config中连接字符串的方法。分享给大家供大家参考。具体如下:
连接字符串中包含数据库的访问信息,帐号和密码,因此一般不以明文显示,本代码用来加密连接字符串。
- public static class EncryptConnection
- {
- public static void EncryptConnectionString(bool encrypt)
- {
- Configuration configFile = null;
- try
- {
- // Open the configuration file and retrieve the connectionStrings section.
- configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
- ConnectionStringsSection configSection = configFile.GetSection("connectionStrings") as ConnectionStringsSection;
- if ((!(configSection.ElementInformation.IsLocked)) && (!(configSection.SectionInformation.IsLocked)))
- {
- if (encrypt && !configSection.SectionInformation.IsProtected)
- //encrypt is false to unencrypt
- {
- configSection.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
- }
- if (!encrypt && configSection.SectionInformation.IsProtected)
- //encrypt is true so encrypt
- {
- configSection.SectionInformation.UnprotectSection();
- }
- //re-save the configuration file section
- configSection.SectionInformation.ForceSave = true;
- // Save the current configuration.
- configFile.Save();
- }
- }
- catch (System.Exception ex)
- {
- throw (ex);
- }
- finally
- {
- }
- }
- }
希望本文所述对大家的C#程序设计有所帮助。
