AutoMapper中IValueFormatter的替代方法是什么? [英] What's the alternative to IValueFormatter in AutoMapper?

问题描述

因此，我开始为我的ASP.NET MVC项目使用AutoMapper，查看了几个示例，并在为IValueFormatter突然弹出一个蓝色提示时写了我的第一个IValueFormatter实现:接口'AutoMapper.IValueFormatter'已过时:不被使用".好吧，那我该怎么办将DateTime转换为字符串吗?

So I started using AutoMapper for my ASP.NET MVC project, looked at a couple of examples and wrote my first IValueFormatter implementation when a blue wiggly popped up for IValueFormatter: Interface 'AutoMapper.IValueFormatter' is obsolete: "Formatters should not not be used". Well, okay, then how am I supposed to e.g. convert a DateTime to, say, a string?

推荐答案

只需为属性创建映射，而无需使用IValueFormatter.例如:

Just create mapping for the property without using IValueFormatter. For example:

Mapper.CreateMap<DbItem, ItemView>()                  
    .ForMember(item => item.DateCreated, opt => opt.ResolveUsing(i => {
        var date = i.DateCreated;
        return date.ToShortDateString();                      
    }));

而不是:

Mapper.CreateMap<DbItem, ItemView>().ForMember(item => item.DateCreated, 
item => item.AddFormatter<ItemDateCreatedFormater>());
