配置 Automapper 以相同的方式映射给定类的所有字符串

Question

源对象中的所有字符串均以逗号分隔。我希望避免代码重复并让 Automapper 以相同的方式处理所有

string

属性。

我是这样实现的：

CreateMap<SourceClass, TargetClass>()
    .ForMember(dest => dest.A, expression => expression.MapFrom(source => source.A.Split(",", StringSplitOptions.TrimEntries)))
    .ForMember(dest => dest.B, expression => expression.MapFrom(source => source.B.Split(",", StringSplitOptions.TrimEntries)))
    .ForMember(dest => dest.C, expression => expression.MapFrom(source => source.C.Split(",", StringSplitOptions.TrimEntries)))
    .ForMember(dest => dest.D, expression => expression.MapFrom(source => source.D.Split(",", StringSplitOptions.TrimEntries)));

但是如您所见，代码被复制了几次。如何避免？

我在单个班级的配置文件级别尝试过，但不知道该怎么做：

ValueTransformers.Add<string>(val => val.Split(",", StringSplitOptions.TrimEntries));

但它不会编译为

Split

返回

string[]

.
