问题描述

当我收到此异常时，是否有某种方法可以从automapper中获取更多详细信息:

Is there some way to get some more detail from automapper when I get this exception:

AutoMapper.AutoMapperMappingException

通常它会告诉我这两种映射类型，但是不会告诉我哪个解析器或部分映射失败.

Often it will tell me the 2 types of the mapping, but not which resolver or part of the mapping is failing.

推荐答案

简单的答案是，最好在您的单元测试中调用此方法.
