c# - “AutoMapper.AutoMapperMappingException”发生在 AutoMapper.dll 中，但未在用户代码中处理

Question

_quatationRepository = new QuatationRepository();
IList<Quatation> quatationObj = _quatationRepository.GetAll(quatation => quatation.IsDeleted == 0);
IList<QuatationModel> quatationModelObj = new List<QuatationModel>();

AutoMapper.Mapper.CreateMap<Quatation, QuatationModel>();
quatationModelObj = AutoMapper.Mapper.Map(quatationObj, quatationModelObj);
return quatationModelObj;

您必须确保具有相同名称的属性具有相同的类型。例如，一侧的 int 和另一侧的 Nullable 将不起作用 (IsDeleted)。
