AutoMapper模型映射

1：安装2个包

AutoMapper 和AutoMapper.Extensions.Microsoft.DependencyInjection

 

实体类：

[SugarTable("UserInfo")]
public class UserInfo
{

[SqlSugar.SugarColumn(IsPrimaryKey =true,IsIdentity =true)]
public int Id { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
}

 

实体Dto

namespace Model.ViewModel
{
public class UserInfoDto
{
public string UserName { get; set; }
public string Password { get; set; }
}
}

 

 

2：新建文件夹Automapper

 

using AutoMapper;
using AutoMapper.Configuration;
using Model.Model;
using Model.ViewModel;
namespace webapi_demo.Automapper
{
public class AutomapperConfig: Profile
{

public AutomapperConfig()
{
CreateMap<UserInfo, UserInfoDto>();
}
}
}

3：Program.cs注入

 

using Common;
using System.Reflection;
using webapi_demo.Automapper;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers();
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Services.AddAutoMapper(typeof(AutomapperConfig));

 

 4 ：控制器引用

 

public UserInfoController(UserInfoService UserService, IMapper map)
{
_service = UserService;
_map = map;
}

 

[HttpGet]
public async Task<UserInfoDto> GetUser(int id)
{
var user = await _service.QueryByID(id);
UserInfoDto dto = new UserInfoDto();
_map.Map(user, dto);
return dto;
}
