Question

我在谷歌搜索但我没有找到解决方案来解决该错误。我正在尝试创建缓存管理器的实例，但获得异常。我使用的是Enterprise library 5.0。我找不到我的问题。我完全陷入困境。任何提示都很明显。

ICacheManager cachManager = EnterpriseLibraryContainer.Current.GetInstance<ICacheManager>();

或

var cm = CacheFactory.GetCacheManager("Cache Manager");

Answer 1

当我从v.5.0.414.0升级到5.0.505.0版时，我遇到了同样的问题。在我的情况下，我必须确保在调用CacheFactory.GetCacheManager(..)之前执行以下操作并且它再次正常工作。

     // first call this
     Container.AddNewExtension<EnterpriseLibraryCoreExtension>();
     // and then
     ICacheManager cacheManager = CacheFactory.GetCacheManager("Cache Manager");

尝试获取ICacheManager类型的实例时出现激活错误，键\“\”“
