這段代碼爲什麼會拋出automapping異常？

Question

我正在做一個內部用戶非工作狀態監視工作，並且我正在使用一個Windows窗體和一個頂棚服務一起執行此操作，代碼將寫入一個RabbitMQ服務器並且該服務將消耗這些消息並轉發它們到一個數據庫，我的代碼，因爲它是拋出一個異常與以下錯誤;

Missing type map configuration or unsupported mapping. 

Mapping types: 
LogData -> DbLogData 
AccessEye.LogData -> AccessEye.DbLogData 

這是代碼爲我服務

不要你需要創建一個地圖在你可以使用之前;

AutoMapper.Mapper.CreateMap<LogData, DbLogData>();
