1.安装automapper的nuget包
AutoMapper.Extensions.Microsoft.DependencyInjection
2.创建需要映射的类和转换后的类

public class studto{public int sn { get; set; }public string name { get; set; }public string sex { get; set; }public int age { get; set; }public string addre { get; set; }}public class stu{public int sn { get; set; }public string name { get; set; }public string sex { get; set; }public int age { get; set; }public string address { get; set; }}

3.创建映射类需要继承automapper中的profile类

 public class customProfile : Profile{public customProfile(){          //如果dto类中的字段和实体类中的字段名相同就不需要配置字段，字段不相同，则要配置CreateMap<stu, studto>()//stu类映射到studto类上，studto类中的addre,与stu类中的address类对应CreateMap<stu, studto>().ForMember(dest => dest.addre, opt => opt.MapFrom(src => src.address));}}

4.在program中注入automapper服务

builder.Services.AddAutoMapper(typeof(customProfile));
builder.Services.AddScoped<Iservice, service>();

5.准备好实体数据

public interface Iservice{List<stu> lsstu();}
public class service : Iservice{public List<stu> lsstu(){List<stu> stus = new List<stu>();stus.Add(new stu() { sn = 1, name = "pzx", sex = "nan", age = 10, address = "pzx" });stus.Add(new stu() { sn = 2, name = "pzx", sex = "nan", age = 10, address = "pzx" });stus.Add(new stu() { sn = 3, name = "pzx", sex = "nan", age = 10, address = "pzx" });return stus;}}

6.在控制中通过构造函数注入的方式调用automapper的map方法，完成实体转换

 [HttpGet]public IActionResult Index(){var ls = iservice.lsstu();var dtols = _mapper.Map<List<stu>, List<studto>>(ls)}

调用效果
