1. 第一种方法，推荐！

添加一个功能类

using AutoMapper;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace AutoMapperTest2{    public static class AutoMapperConfig    {        public static IMapper Mapper = new Mapper(RegisterMappings());        public static MapperConfiguration RegisterMappings()        {            return new MapperConfiguration(cfg =>            {                cfg.CreateMissingTypeMaps = true;                cfg.AllowNullDestinationValues = false;                cfg.ForAllPropertyMaps(IsToRepeatedField, (propertyMap, opts) => opts.UseDestinationValue());                cfg.ForAllPropertyMaps(IsToMapFieldField, (propertyMap, opts) => opts.UseDestinationValue());                cfg.AddProfile
     
      ();            });            bool IsToRepeatedField(PropertyMap pm)            {                if (pm.DestinationPropertyType.IsConstructedGenericType)                {                    var destGenericBase = pm.DestinationPropertyType.GetGenericTypeDefinition();                    return false;// destGenericBase == typeof(RepeatedField<>);                }                return false;            }            bool IsToMapFieldField(PropertyMap pm)            {                if (pm.DestinationPropertyType.IsConstructedGenericType)                {                    var destGenericBase = pm.DestinationPropertyType.GetGenericTypeDefinition();                    return false;// destGenericBase == typeof(MapField<,>);                }                return false;            }        }    }    public class OutputModels : Profile    {        public OutputModels()        {        }    }}
     

使用

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace AutoMapperTest2{    class Program    {        static void Main(string[] args)        {            var src = new source() {                name = "jeff",                age  = 1,                strList = new List
     
      () { "1", "2", "3"},                classList = new List
      
       ()                {                    new aaa(){a1="a1", a2=1},                     new aaa(){a1="a2", a2=2},                      new aaa(){a1="a3", a2=3},                }            };            var tgt = AutoMapperConfig.Mapper.Map
       
        (src);            if (tgt != null)                Console.WriteLine($"name = {tgt.name}");        }    }    public class source    {        public string name { get; set; }        public int age { get; set; }        public List
        
          strList { get; set; }        public List
         
           classList { get; set; }    }    public class target    {        public string name { get; set; }        public int age { get; set; }        public List
          
            strList { get; set; } public List
           
             classList { get; set; } } public class aaa { public string a1 { get; set; } public int a2 { get; set; } }}
           
          
         
        
       
      
     

 

 

2. 第二种方法：

添加功能类

using AutoMapper;using System;using System.Collections.Generic;using System.Linq;using System.Web; namespace TCG.DataCollection.Webservice{    public sealed class Mapper    {        private static readonly Mapper instance = new Mapper();        private Mapper()        {            this.Init();        }        public void Init()        {            AutoMapper.Mapper.Initialize(cfg =>            {                departmentMapping(cfg);                this.employeeMapping(cfg);this.defaultMapping

使用时

var model = Mapper.Map
     
      (data);
