我正在使用 AutoMapper 映射两个对象，但它不是映射int.

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，它返回一个类型，object但 ints 始终为空。

真实课程的问题

public class SearchRawInput
{
    public SearchRawInput()
    {
        PageNo = 1;
    }
    public string City { get; set; }
    public string Segment1 { get; set; }
    public string Segment2 { get; set; }
    public TargetAgeGroup? TargetAge { get; set; }
    public List<int> CategoryIds { get; set; }
    public List<int> SubCategoryIds { get; set; }
    public List<int> LocationIds { get; set; }
    public List<int> LocationGroupIds { get; set; }
    public DateTime? StartDate { get; set; }
    public DateTime? EndDate { get; set; }
    public decimal? StartPrice { get; set; }
    public decimal? EndPrice { get; set; }
    public string SearchQuery { get; set; }
    public int? PageNo { get; set; }

}

public class ClassSearchInputViewModel
{
    public ClassSearchInputViewModel()
    {
        PageSize = 12;
    }
    public UrlSeoProcessingResult UrlSeoProcessingResult { get; set; }
    public TargetAgeGroup TargetAge { get; set; }
    public List<int> CategoryIds { get; set; }
    public List<int> SubCategoryIds { get; set; }
    public List<int> LocationIds { get; set; }
    public List<int> LocationGroupIds { get; set; }
    public DateTime? StartDate { get; set; }
    public DateTime? EndDate { get; set; }
    public decimal? StartPrice { get; set; }
    public decimal? EndPrice { get; set; }
    public ClassDifficultyLevel DifficultyLevel { get; set; }
    public string SearchQuery { get; set; }
    public int PageNo { get; set; }
    public int PageSize { get; set; }
}

public class SegmentToUrlSeoProcessingResultResolver : ValueResolver<SearchRawInput, UrlSeoProcessingResult>
{
    protected  override UrlSeoProcessingResult ResolveCore(SearchRawInput source)
    {
        var processor =new UrlProcessor();
        if (source.Segment1 != null && source.Segment2 != null)
        {
            return processor.Process( (source.Segment1.Trim() + "/" + source.Segment2.Trim()).Trim(), source.City);
        }
        else if (source.Segment1 == null && source.Segment2 == null)
        {
            return processor.Process("", source.City);
        }
        else
        {
            if (source.Segment1 != null)
            {
                return processor.Process( (source.Segment1.Trim()).Trim(),source.City);
            }
            else 
            {
                return processor.Process(  source.Segment2.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>());

以上是完整的代码，当我调用 ClassSearchRawInputToClassSearchInputmethod 时，它将返回 ClassSearchInputViewModel 的对象，但它返回的 locationids 为 0 而不是项目

这是我的单元测试

抱歉，我无法使用可用的最新 AutoMapper NuGet (2.2.1) 重现您描述的问题：

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 2 种类型之间进行映射。所以我猜你没有显示你的真实代码。您必须展示一个完整的示例来说明您的问题。
