.Net Mvc AutoMapper简单使用

1、安装automapper nuget包。

2、新建一个AutoMapper配置类并实现一个静态配置方法。

方法一、

using AutoMapper;
using AutoMapperTest.Models;

namespace AutoMapperTest.App_Start
{
public class AutoMapperConfig
{
public static void Config()
{
Mapper.Initialize(cfg =>
{
cfg.CreateMap<StudentEntity, StudentOutput>();
});
}
}
}

方法二、AddProfile方式

using AutoMapper;
using AutoMapperTest.Models;

namespace AutoMapperTest.App_Start
{
public class AutoMapperConfig
{
public static void Config()
{
Mapper.Initialize(cfg =>
{
cfg.AddProfile<MapperProfile>();
});
}
}
}

using AutoMapper;
using AutoMapperTest.Models;

namespace AutoMapperTest.App_Start
{
public class MapperProfile : Profile
{
public MapperProfile()
{
CreateMap<StudentEntity, StudentOutput>();
}
}
}

3、在全局配置Global.asax中引用配置方法。

using AutoMapperTest.App_Start;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;

namespace AutoMapperTest
{
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AutoMapperConfig.Config();
}
}
}

4、具体使用

public JsonResult GetMapper()
{
//实例化实体List
List<StudentEntity> StudentList = new List<StudentEntity>();
//模拟数据
StudentList.Add(new StudentEntity
{
Id = 1,
Age = 12,
Gander = "boy",
Name = "WangZeLing",
Say = "Only the paranoid survive",
Score = 99M
});
//AuotMapper具体使用方法 将List<StudentOutput>转换为List<StudentOutput>
List<StudentOutput> Output = AutoMapper.Mapper.Map<List<StudentOutput>>(StudentList);
return Json(Output, JsonRequestBehavior.AllowGet);
}

附：实体类、Output类

public class StudentEntity
{
public int Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public string Gander { get; set; }
public decimal Score { get; set; }
public string Say { get; set; }
}

public class StudentOutput
{
public string Name { get; set; }
public decimal Score { get; set; }
public string Say { get; set; }
}
