如何通过此代码从属性映射中获取源属性的名称:

How do I get the name of the source property from the property map in this code:

IEnumerable<PropertyMap> propertyMapList = Mapper.FindTypeMapFor<TFrom, TTo>().GetPropertyMaps(); foreach (PropertyMap propertyMap in propertyMapList) { ////..... }

推荐答案

这应该在AutoMapper v1中有效(尚未在v2中尝试过).

This should work in AutoMapper v1 (haven't tried in v2 yet).

foreach (PropertyMap propertyMap in propertyMapList) { var resolver = propertyMap.GetSourceValueResolvers().First(); var getter = (IMemberGetter) resolver; var info = getter.MemberInfo; }

这假定它只是从一个属性到另一个属性的沼泽标准地图，否则它将无法正常工作.因此，显然，您将需要在演员表等周围添加错误检查.

This assumes that it's just a bog-standard map from one property to another, it won't work otherwise. So, obviously, you'll want to add error checking around the cast, etc.
