AutoMapper 8.0 缺少 GetPropertyMaps [英] AutoMapper 8.0 missing GetPropertyMaps

问题描述

在 AutoMapper 8.0 之前，我使用此代码通过字符串查找属性映射，例如:实体模型具有名为currency_id"的属性，而 DTO 具有名为currency"的属性.我在 AutoMapper 中定义了双向映射，我用这段代码来查找源/目标属性相关

Prior to AutoMapper 8.0, I used this code to find a property mapping by string, example: entity model has property named "currency_id" and DTO has property named "currency". I have defined bi-directional mapping in AutoMapper, and I used this code to find source/target property relat

    public static string GetDestinationPropertyFor<TSrc, TDst>(IMapper IMapper, string sourceProperty)
    {
        var mapper = AutoMapper.IMapper.ConfigurationProvider;

        // TSrc = source generic type
        // TDst = destination generic type
        var map = mapper.FindTypeMapFor<TSrc, TDst>();

        var propertyMap = map.GetPropertyMaps()
                              .FirstOrDefault(pm => 
                                    pm.SourceMember.Name == sourceProperty
                              );


        return propertyMap.DestinationProperty.Name;
    }

在 AutoMapper 配置文件中:

In AutoMapper Profile:

        this.CreateMap<EntityModels.contact, DTO.contact>()
            .ForMember(m => m.currency, src => src.MapFrom(f => f.currency_id))
        ;

        this.CreateMap<DTO.contact, EntityModels.contact>()
            .ForMember(m => m.currency_id, src => src.MapFrom(f => f.currency))
        ;

当我这样调用我的方法时:

When I called my method like this:

var _dboField = GetDestinationPropertyFor<DTO.contact, EntityModels.contact>(this.mapper, "currency");

Console.WriteLine(_dboField);
// output should be "currency_id"

升级到 AutoMapper 8.0 后，我在构建时遇到此错误:

After upgrading to AutoMapper 8.0 I got this error at build:

TypeMap"不包含GetPropertyMaps"的定义，并且找不到接受TypeMap"类型的第一个参数的可访问扩展方法GetPropertyMaps"(您是否缺少 using 指令或程序集引用?)

'TypeMap' does not contain a definition for 'GetPropertyMaps' and no accessible extension method 'GetPropertyMaps' accepting a first argument of type 'TypeMap' could be found (are you missing a using directive or an assembly reference?)

AutoMapper 8.0 中 GetPropertyMaps 的替代品是什么?

What are replacements for GetPropertyMaps in AutoMapper 8.0?

谢谢！

推荐答案

正如 Lucian 所建议的，MemberMaps 是一个可能的替代品.但是，PropertyMaps 与 AutoMapper 7.0 中的 GetPropertyMaps 完全相同.DestinationProperty 也被重命名为 DestinationMember.

As Lucian suggested, MemberMaps is a possible replacement. However, PropertyMaps does exactly the same as GetPropertyMaps in AutoMapper 7.0. DestinationProperty has also been renamed to DestinationMember.

AutoMapper 7.0 代码:

AutoMapper 7.0 code:

public static string GetDestinationPropertyFor<TSrc, TDst>(IMapper IMapper, string sourceProperty)
    {
        var mapper = AutoMapper.IMapper.ConfigurationProvider;

        // TSrc = source generic type
        // TDst = destination generic type
        var map = mapper.FindTypeMapFor<TSrc, TDst>();

        var propertyMap = map.GetPropertyMaps()
                              .FirstOrDefault(pm => 
                                    pm.SourceMember.Name == sourceProperty
                              );


        return propertyMap.DestinationProperty.Name;
    }

AutoMapper 8.0 代码:

AutoMapper 8.0 code:

public static string GetDestinationPropertyFor<TSrc, TDst>(IMapper IMapper, string sourceProperty)
    {
        var mapper = AutoMapper.IMapper.ConfigurationProvider;

        // TSrc = source generic type
        // TDst = destination generic type
        var map = mapper.FindTypeMapFor<TSrc, TDst>();

        var propertyMap = map.PropertyMaps
                              .FirstOrDefault(pm => 
                                    pm.SourceMember.Name == sourceProperty
                              );


        return propertyMap.DestinationMember.Name;
    }
