.net 使用AutoMapper 做对象赋值

步骤1：项目引用

AutoMapper

AutoMapper.Extensions.Microsoft.DependencyInjection

步骤2：建立文件 DevProCommonFile

IProfile：是一个空接口，主要用来动态加载文件时查找相关文件，也就时说DevProCommonFile这种文件可以建立多个，只要继承

Profile, IProfile就会被框架加入

using AutoMapper;
using Dev.WooNet.Model.DevDTO;
using Dev.WooNet.Model.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Dev.WooNet.AutoMapper.ProFiles
{

    /// <summary>
    /// 公共映射文件
    /// </summary>
    public class DevProCommonFile : Profile, IProfile
    {
        public DevProCommonFile()
        {
            CreateMap<DepartData, DevDepartment>();
          //.ForMember(a => a.ContId, opt => opt.Ignore())
          //.ForMember(a => a.CreateUserId, opt => opt.Ignore())
          //.ForMember(a => a.CreateDateTime, opt => opt.Ignore())
          //.ForMember(a => a.ModifyUserId, opt => opt.Ignore())
          //.ForMember(a => a.ModifyDateTime, opt => opt.Ignore());
        }
       
    }
}

步骤3：设置加载文件规则

建立Mappings 定一个扩展方法AddDevMapperFiles

using AutoMapper;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;

namespace Dev.WooNet.AutoMapper.Extend
{
   public static class Mappings
    {
      

        /// <summary>
        ///映射文件
        /// </summary>
        /// <param name="service"></param>
        public static void AddDevMapperFiles(this IServiceCollection service)
        {
            var allType =
          Assembly
             .GetEntryAssembly()//获取默认程序集
             .GetReferencedAssemblies()//获取所有引用程序集
             .Select(Assembly.Load)
             .SelectMany(y => y.DefinedTypes)
             .Where(type => typeof(IProfile).GetTypeInfo().IsAssignableFrom(type.AsType()));
            service.AddAutoMapper(allType.ToArray());

            

        }
    }
}

步骤4：Startup 的ConfigureServices进行注册

services.AddDevMapperFiles();（上面扩展方法）

步骤5：应用在控制器注入 IMapper

private IMapper _IMapper { get; set; }

然后 var deptinfo = _IMapper.Map<DevDepartment>(departData);

这样就完成了AutoMapper使用
