获取声明为动态的对象的类型 [英] get the Type for a object declared dynamic

问题描述

我想获取动态对象的类型，例如:

I would like to get the Type for an dynamic object, something like:

dynamic tmp = Activator.CreateInstance(assembly, nmspace + "." + typeName);
Type unknown = tmp.GetType();

除了上面的，GetType() 返回的是动态对象的包装器类型，而不是被包装对象的类型.谢谢！

Except that in the above, GetType() returns the type of the wrapper for dynamic objects not the type of the wrapped object. Thanks!

推荐答案

你需要这样做...

Type unknown = ((ObjectHandle)tmp).Unwrap().GetType();

顺便说一句，这有点令人困惑，因为如果您在当前程序集中的类型上调用 Activator.CreateInstance...

By the way, this is a little confusing because if you call Activator.CreateInstance on a type in your current assembly...

Activator.CreateInstance(typeof(Foo))

...对象没有被包装，原始代码工作正常.

...the object is not wrapped and the original code works fine.
