Question

我正在使用AutoMapper dll。尝试编写一种映射过程的方法。

    public ServiceResult<LoginModel> Login(LoginModel model)
    {
            //-----from here
            var config = new MapperConfiguration(cfg => {
                cfg.CreateMap<LoginModel, User>();
            });

            IMapper mapper = config.CreateMapper();
            var user = new User();

            var dest = mapper.Map<LoginModel, User>(model);
            //------ to here

            return new ServiceResult<LoginModel>(model);
    }

因此，我需要将LoginModel，User和Model设置为动态。该方法应该简单地如下所示（仅举例来说，我找不到一种方法），

 public object Map(Type source, Type destination, object model)
{
        var config = new MapperConfiguration(cfg => {
            cfg.CreateMap<source, destination>();
        });

        IMapper mapper = config.CreateMapper();
        var user = new User(); (Model of [destination])

        var dest = mapper.Map<source, destination>(model);
        //map data from model to dest

        return new ServiceResult<LoginModel>(model);
}

您可以将Map方法更改为通用方法：

public object Map<TSource, TDestination>(object model)
        {
            var config = new MapperConfiguration(cfg => {
                cfg.CreateMap<TSource, TDestination>();
            });

            IMapper mapper = config.CreateMapper();
            var user = new User();

            var dest = mapper.Map<TSource, TDestination>(model);
            //map data from model to dest

            return new ServiceResult<LoginModel>(model);
        }

使用类型作为参数
