如何检查是否一个泛型参数是动态的，在.NET 4.0中
问题描述：
我有一个类 ObjectMapper＆LT; T＆GT; 。有没有办法在.NET 4.0中说，如果的typeof（T）是动态？我希望能够确定一个成员方法的类是否被初始化为新ObjectMapper＆LT内部;动态＆GT;（）与新ObjectMapper＆LT; SomeConcreteClass＆GT; （）。
I have a class ObjectMapper<T> . Is there any way in .NET 4.0 to tell if typeof(T) is dynamic? I want to be able to determine inside a member method whether the class was initialized as new ObjectMapper<dynamic>() vs. new ObjectMapper<SomeConcreteClass>().
答
为此，您需要检查，如果一个实例的类型是 IDynamicMetaObjectProvider ，也可以检查是否类型实现 IDynamicMetaObjectProvider 。
You do this by checking if an instance is of type IDynamicMetaObjectProvider or you can check whether the type implements IDynamicMetaObjectProvider.
