大小（）等效引用类型？ [英] sizeof() equivalent for reference types?

问题描述

我在寻找一种方式来获得一个引用类型的实例的大小。 sizeof的仅仅是值类型。这可能吗？

I'm looking for a way to get the size of an instance of a reference type. sizeof is only for value types. Is this possible?

推荐答案

如果你不介意它是一个小完美的不准确，并为比较的目的，你可以序列化对象/ s和衡量（以字节为单位例如）

If you don't mind it being a little less accurate than perfect, and for comparative purposes, you could serialize the object/s and measure that (in bytes for example)

编辑（我一直在发布后的思考）的：因为​​它是一个多一点的sizeof值类型的更复杂，例如：引用类型可以有对其他对象等等......有没有一个准确，简单的方法来做到这一点，我知道了......

EDIT (I kept thinking after posting): Because it's a little more complicated than sizeof for valuetypes, for example: reference types can have references to other objects and so on... there's not an exact and easy way to do it that I know of...
