在AutoMapper中映射子列表属性上的“计数" [英] Mapping the 'count' on child list property in AutoMapper

问题描述

我正在ASP.NET MVC 4应用程序中工作，对于我的域也有类似的东西.

I am working in an ASP.NET MVC 4 application, and have something similar to this for my domain.

public class Party
{
    public Cake PartyCake { get; set; }
    public List<Candles> CakeCandles { get; set; }
}

我想将其映射到如下所示的PartyVM:

I want to map that to the PartyVM which looks like so:

public class PartyVM
{
    public string PartyCakeName { get; set; }
    public int CandlesCount { get; set; }
}

在进行映射时，如何告诉AutoMapper计算列表的计数?我有这个，但是所有要做的就是告诉它忽略！

How can I tell AutoMapper to work out the Count of the list when doing its mappings? I have this, but all this does is tell it to ignore!

Mapper.CreateMap<Party, PartyVM>()
            .ForMember(dest => dest.CandlesCount, opt => opt.Ignore());

谢谢.

推荐答案

AutoMapper支持开箱即用，您的目标成员名称不正确.如果您将PartyVM属性命名为"CakeCandlesCount"，它将具有正确的值.

AutoMapper supports Count out of the box, your destination member is just named incorrectly. If you name your PartyVM property "CakeCandlesCount" it will have the right value.
