尝试获取ICacheManager类型的实例时出现激活错误，键“Cache Manager”
我似乎在这里遇到了障碍，并希望得到任何能够在这一方面得到帮助的人。 我不确定下面的错误消息是什么意思。 我正在使用企业模式服务的缓存块，但我继续遇到下面的问题。 我下载了最新版本，并尝试逐步解决这个问题，但我似乎无法解决确切的问题，我需要帮助。 提前致谢

var cm = CacheFactory.GetCacheManager("MyCacheManager");
要获取CacheManager ，您需要在app.config或web.config中定义CacheManager ：
添加配置值后，您应该能够从CacheFactory获取有效的CacheManager 。 该post还有一些可能对您有帮助的信息。
值得注意的是，如果您使用的是.NET 4.0，对于非Web应用程序，您可以使用MemoryCache （在System.Runtime.Caching命名空间中），它提供类似的function，但不需要所有这些配置。 对于Web应用程序，您当然可以在System.Web.Caching使用Cache类。
