Question

我使用AutoMapper映射两个对象，但它不映射int的列表。

这是我正在做的事情：

Public class A
{
    public int a{get;set;}
    public string b{get;set;}
    public List<int> ints{get;set;}
}

Public class B
{
    public int a{get;set;}
    public string b{get;set;}
    public List<int> ints{get;set;}
}

public class MappingService
{

    public object MapBToA(B b)
   {
        Mapper.CreateMap<B,A>();
        return  Mapper.Map<B,A>(b);
   }
}

当我们调用映射函数时，它返回的是object类型，但是int总是空的。

            return processor.Process( (source.Segment1.Trim() + "/" + source.Segment2.Trim()).Trim(), source.City);

    }

public ClassSearchInputViewModel ClassSearchRawInputToClassSearchInput(SearchRawInput classSearchRawInput)
    {
        var classSearchInput = Mapper.Map<SearchRawInput, ClassSearchInputViewModel>(classSearchRawInput);
        return classSearchInput;
    }

Mapper.CreateMap<SearchRawInput,ClassSearchInputViewModel>()
    .ForMember(dest => dest.UrlSeoProcessingResult, opt => opt.ResolveUsing<SegmentToUrlSeoProcessingResultResolver>());

上面是完整的代码，当我调用ClassSearchRawInputToClassSearchInput方法时，它将返回ClassSearchInputViewModel的对象，但它返回的是0而不是item的locationids

抱歉，我无法使用最新的AutoMapper NuGet（2.2.1）重现您所描述的问题：

using System;
using System.Collections.Generic;
using AutoMapper;

public class A
{
    public int a { get;set; }
    public string b { get;set; }
    public List<int> ints { get;set; }
}

public class B
{
    public int a { get;set; }
    public string b { get;set; }
    public List<int> ints { get;set; }
}

class Program
{
    static void Main()
    {
        Mapper.CreateMap<B, A>();
        var b = new B
        {
            a = 1,
            b = "foo",
            ints = new List<int>(new[] { 1, 2, 3, 4 })
        };

        var a = Mapper.Map<B, A>(b);
        Console.WriteLine(a.ints.Count);
        foreach (var item in a.ints)
        {
            Console.WriteLine(item);
        }
    }
}

此控制台应用程序按预期在两种类型之间进行映射。所以我猜你没有展示你真正的代码。您必须显示一个说明问题的完整示例。
