automapper地图动态对象 [英] automapper map dynamic object

问题描述

我与Automapper工作，需要实现以下映射，但不知道它是如何完成的。

I am working with Automapper and need to achieve the following mapping but not sure how it can be done.

我要Dictionary对象映射到一个动态对象，因此，关键是对象和字典的值的属性是在动态对象属性的值。

I want to map a Dictionary object to a dynamic object, so that the key is the property on the object and the value of the dictionary is the value of property in dynamic object.

可这是与automapper若然实现怎么样？

Can this be achieve with automapper and if so, how?

推荐答案

您可以简单地获得词典从 ExpandoObject 并与原有的字典中的值填充

You can simply get Dictionary from ExpandoObject and fill it with original dictionary values

void Main()
{
    AutoMapper.Mapper.CreateMap<Dictionary<string, object>, dynamic>()
                     .ConstructUsing(CreateDynamicFromDictionary);

    var dictionary = new Dictionary<string, object>();
    dictionary.Add("Name", "Ilya");

    dynamic dyn = Mapper.Map<dynamic>(dictionary);

    Console.WriteLine (dyn.Name);//prints Ilya
}

public dynamic CreateDynamicFromDictionary(IDictionary<string, object> dictionary)
{
    dynamic dyn = new ExpandoObject();
    var expandoDic = (IDictionary<string, object>)dyn;

    dictionary.ToList()
              .ForEach(keyValue => expandoDic.Add(keyValue.Key, keyValue.Value));
    return dyn;
}
