是否可以知道 System.Object 是否实际上被指定为动态 (C#)？

我有几个场景涵盖了这一点，但我将专门写一个更容易证明

我有一个工厂接口的场景：

interface IFactory
{
  Create<T>();
}

以及一段使用它的代码：

public static void func(IFactory f)
{
  var o = f.Create<dynamic>();
}

现在，在 Create的实现中T>() - 有没有办法通过 T 反射来确定调用者是否打算在其对象上进行动态分派，而不是直接的对象?我有一个类，能够做出这种区分将非常有用......

我已经查看了是否可以找到类型的属性或类似的东西，但没有乐趣。

I have a couple of scenarios that cover this, but I'll write specifically about the one that's easier to demonstrate

I have a factory interface:

interface IFactory
{
  Create<T>();
}

And a piece of code that uses it thus:

public static void func(IFactory f)
{
  var o = f.Create<dynamic>();
}

Now, in an implementation of Create<T>() - is is there any way, via reflection over T, to determine if the caller is intending dynamic dispatch on their object as opposed to a straightforward object? I have a class where being able to make that distinction would be quite useful...

I've had a look to see if I can find attributes on the type or something like that, but no joy.
