AutoMapper C#实体映射

Posted 2021-01-26 xiasy-bk

AutoMapper是对象到对象的映射工具。在完成映射规则之后，AutoMapper可以将源对象转换为目标对象。

要映射实体

1  public class SourceModel
2     {
3         public int ID { get; set; }
4         public string Name { get; set; }
5         public string Address { get; set; }
6         public string Mobile { get; set; }
7     }

被映射实体

1  public class YingSheModel
2     {
3         public string Name { get; set; }
4         public string Address { get; set; }
5     }

View Code

需要将SourceModel类的对象映射到YingSheModel类的对象上面。需要对AutoMapper进行如下配置：

//注：Mapper.CreateMap由于nuget的最新版本用法改变了无法使用

Mapper.Initialize(cret => cret.CreateMap<SourceModel, YingSheModel>())

效果展示：

 

全部代码：

using AutoMapper;
using System;

namespace Mapping
{
    class Program
    {
        static void Main(string[] args)
        {
            Mapper.Initialize(cret => cret.CreateMap<SourceModel, YingSheModel>());//配置
            SourceModel sources = new SourceModel() { ID = 1, Name = "特朗普", Address = "北京市洪山区", Mobile = "18712457845" }; //给实体赋初始数据
            YingSheModel dest = Mapper.Map<YingSheModel>(sources);//看这里的断点
            var model = new
             {
                name = dest.Name,
                address = dest.Address
             };
             Console.WriteLine(model);
             Console.ReadKey();

        }

    }
    public class SourceModel
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public string Mobile { get; set; }
    }
    public class YingSheModel
    {
        public string Name { get; set; }
        public string Address { get; set; }
    }
}
