我有一个具有ConcurrentDictionary字段的对象。 访问Ignite共享内存中的数据时，出现以下错误。
System.InvalidCastException: [A]System.Collections.Concurrent.ConcurrentDictionary'2[System.String,CampaignEngine.Model.LookupItem] cannot be cast to [B]System.Collections.Concurrent.ConcurrentDictionary'2[System.String,CampaignEngine.Model.LookupItem].

为什么不能点燃反序列化ConcurrentDictionary？
谢谢...
答案 0 :(得分：0)
好像您在代码中的某个位置导入了问题，可能是由于Why is Visual Studio telling me I need to reference System.Private.CoreLib?
检查您的任何源文件以引用System.Private.CoreLib，并将其替换为System.Collections.Concurrent。
