有没有一种方法，以动态或匿名对象转换为强类型，声明的对象？ [英] Is there a way to convert a dynamic or anonymous object to a strongly typed, declared object?

问题描述

如果我有一个动态的对象，或者匿名对象对于这个问题，它的结构完全匹配，一个强类型的对象，是有一个.NET方法从动态对象建立一个类型的对象？

If I have a dynamic object, or anonymous object for that matter, whose structure exactly matches that of a strongly typed object, is there a .NET method to build a typed object from the dynamic object?

我知道我可以使用LINQ dynamicList.Select（动态=＆gt;新建类型化{......} 键入的东西，或者我可以使用Automapper，但我敢不知道是否有不是特别打造了这一点？

I know I can use a LINQ dynamicList.Select(dynamic => new Typed { .... } type thing, or I can use Automapper, but I'm wondering if there is not something specially built for this?

推荐答案

您可以序列为中间格式，只是为了反序列化后的权利。这不是最优雅的或有效的方式，但它可能让你的工作做好：

You could serialize to an intermediate format, just to deserialize it right thereafter. It's not the most elegant or efficient way, but it might get your job done:

假如这是你的类：

// Typed definition
class C
{
    public string A;
    public int B;
}

这是匿名的实例：

And this is your anonymous instance:

// Untyped instance
var anonymous = new {
    A = "Some text",
    B = 666
};

您可以序列化匿名版本的中间格式，然后再反序列化到一个类型版本。

You can serialize the anonymous version to an intermediate format and then deserialize it again to a typed version.

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var json = serializer.Serialize(anonymous);
var c = serializer.Deserialize<C>(json);

请注意，这是在理论上可能与任何串行器/解串器（的 XmlSerializer的，二进制序列化，其他的JSON库），只要往返是同步的。

Note that this is in theory possible with any serializer/deserializer (XmlSerializer, binary serialization, other json libs), as long as the roundtrip is synchronous.
