我通常会在我的C ++ code做到这一点：

I would normally do this in my C++ code:

int variable = 10;
int sizeOfVariable = sizeof(variable);   //Returns 4 for 32-bit process

但是，这似乎并不适用于C＃。是否有一个模拟？

But that doesn't seem to work for C#. Is there an analog?

推荐答案

在 的sizeof 运营商在C＃中只能在编译时已知类型，而不是变量（实例）。

The sizeof operator in C# works only on compile-time known types, not on variables (instances).

正确的例子是

int variable = 10;
int sizeOfVariable = sizeof(int);

所以，可能是你正在寻找的Marshal.SizeOf它可以用于任何对象实例或运行时类型

So probably you are looking for Marshal.SizeOf which can be used on any object instances or runtime types.

int variable = 10;
int sizeOfVariable = Marshal.SizeOf(variable);
