C# 解决无法识别的属性 configProtectionProvider
在使用.Net自身提供的加密本配置文件后再用System.Configuration.ConfigurationManager.AppSettings["key"]获取值时会出现“无法识别的属性 configProtectionProvider参考”
注意：
- 如果你是自定义加密值再保存到配置文件和则Aspnet_regiis.exe不会出现此问题,即不使用.Net默认的加密方式
- 使用.Net默认加密方式示例
-
Configuration configuration =ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); #region 保存配置文件 try { //加密配置信息 if(isProtected &&!configuration.AppSettings.SectionInformation.IsProtected) { configuration.AppSettings.SectionInformation.ForceSave=true; configuration.AppSettings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider"); } configuration.Save(); } catch(Exception) {
- 使用此加密方式会加密节点下所有的数据
- .Net自身的加密是跟电脑相关的,即在开发者电脑上生成的配置文件发布到生产机器上(包括所有非开始者电脑)都无法获取配置值会出现以下问题
在Google和stackoverflow上搜索都没有解决看来
只有自己动脑啦,经过一番摸索最终解决将自己的解决方案记录如下：
之前的方法：
/// <summary> /// 获取配置文件指定的值 /// </summary> /// <param name="key">健</param> /// <returns>健值</returns> public static string GetConfig(string key) { //如果使用.Net对配置文件进行加密过,则访问ConfigurationManager.AppSettings会产生错误"无法识别的属性 configProtectionProvider" if (string.IsNullOrEmpty(key)||ConfigurationManager.AppSettings[key]==null) return string.Empty; return ConfigurationManager.AppSettings[key]; }
改进后的方法(不直接使用
ConfigurationManager
的AppSettings属性而是打开配置文件再进行访问及读写操作
):
/// <summary> /// 获取配置文件指定的值 /// </summary> /// <param name="key">健</param> /// <returns>健值</returns> public static string GetConfig(string key) { if (string.IsNullOrEmpty(key)) return string.Empty; Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); if (config.AppSettings.Settings[key] == null) return string.Empty; else return config.AppSettings.Settings[key].Value; }
