Question

我正在为内部用户不活动监视器工作，我正在使用windows表单和topshelf服务来执行此操作，代码将写入RabbitMQ服务器，服务将使用消息并转发他们到数据库，我的代码就是抛出以下错误的异常;

Missing type map configuration or unsupported mapping.

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

这是我服务的代码

在使用地图之前，您不需要创建地图;

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

为什么这段代码会引发自动化异常？
