AutoMapper枚举用FPGA实现IMapperConfigurator到字节(AutoMapp

枚举定义

public enum RowStatusEnum
{
    Modified = 1,
    Removed = 2,
    Added = 3
}

public class RowStatusEnumConvertor : IMapperConfigurator
{
    public void Cofigure()
    {
        Mapper.CreateMap<RowStatusEnum, byte>();
        Mapper.CreateMap<byte, RowStatusEnum >();
    }
}

我在RowStatusEnumConvertor类配置autoMapper用FPGA实现IMapperConfigurator，但不起作用此代码，不，我想我的配置不正确或没有足够的映射这种类型的，请帮帮我

谢谢

Answer 1:

我已复制你的问题。 该解决方案是非常简单的，不配置AutoMapper并设置枚举字节的基本类型。 像这样：

public enum RowStatusEnum : byte
{
   Modified = 1,
   Removed = 2,
   Added = 3,
}

要让它正常工作：

byte x = 3;
RowStatusEnum rowStatus = Mapper.Map<RowStatusEnum>(x); 
//The result will be: Added

请问这样的事情对你的工作？

Classes.cs

namespace StackOverflow.RowStatus
{
    public enum RowStatusEnum
    {
        Modified = 1,
        Removed = 2,
        Added = 3
    }
}

AutoMapperConfigurator.cs

namespace StackOverflow.RowStatus
{
    using System;
    using System.Linq;

    using AutoMapper;

    public class MyProfile : Profile
    {
        protected override void Configure()
        {
            Mapper.CreateMap<byte, RowStatusEnum>().ConvertUsing(
                x => Enum.GetValues(typeof(RowStatusEnum))
                         .Cast<RowStatusEnum>().First(y => (byte)y == x));
            Mapper.CreateMap<RowStatusEnum, byte>().ConvertUsing(
                x => (byte)x);
        }
    }
}

MappingTests.cs

namespace StackOverflow.RowStatus
{
    using AutoMapper;

    using NUnit.Framework;

    [TestFixture]
    public class MappingTests
    {
        [Test]
        public void AutoMapper_Configuration_IsValid()
        {
            Mapper.Initialize(m => m.AddProfile<MyProfile>());
            Mapper.AssertConfigurationIsValid();
        }

        [TestCase(1, Result = RowStatusEnum.Modified)]
        [TestCase(2, Result = RowStatusEnum.Removed)]
        [TestCase(3, Result = RowStatusEnum.Added)]
        public RowStatusEnum AutoMapper_ConvertFromByte_IsValid(
                                                   byte rowStatusEnum)
        {
            Mapper.Initialize(m => m.AddProfile<MyProfile>());
            Mapper.AssertConfigurationIsValid();
            return Mapper.Map<byte, RowStatusEnum>(rowStatusEnum);
        }

        [TestCase(RowStatusEnum.Modified, Result = 1)]
        [TestCase(RowStatusEnum.Removed, Result = 2)]
        [TestCase(RowStatusEnum.Added, Result = 3)]
        public byte AutoMapper_ConvertFromEnum_IsValid(
                                                   RowStatusEnum rowStatusEnum)
        {
            Mapper.Initialize(m => m.AddProfile<MyProfile>());
            Mapper.AssertConfigurationIsValid();
            return Mapper.Map<RowStatusEnum, byte>(rowStatusEnum);
        }
    }
}
