托管类型的SizeOf [英] SizeOf for managed types

问题描述

有人知道如何获取托管类型的字节大小吗？


我有哈希表和我想要检查字节大小。我可以使用sizeof获得大小

的值类型与prmitives类型（如int32等）。


谢谢

Hi,

Does anybody know how to get the size in bytes of a managed type?

I have a hashtable and I want to check the size in bytes. I can get the size
using sizeof for value types with prmitives types (like int32, etc).

Thanks

没有可靠的方法可以从
$ b中了解托管对象的大小$ b您的应用程序代码。

为什么您需要检查托管类型的大小？


Willy。

There is no reliable way to know the size of managed objects from within
your application code.
Why would you ever need to check the size of managed types?

请参阅System.Runtime.InteropServices.Marshal.SizeOf（）

不，这将返回对象的大小，因为它将被封送并且可以

只能与值类型（struct）一起使用。


尝试这个...

struct Test

{

公共字符串s;

}


....

测试t =新测试（ ）;

ts ="猜对象大小" ;;

Console.WriteLine（System.Runtime.InteropServices.M arshal.SizeOf（t））;


结果是4，这绝对不是对象t的正确大小。

No, this returns the size of the object as it would be marshaled and can
only be used with value types (struct).

try this...
struct Test
{
public string s;
}

....
Test t = new Test();
t.s = "guess the object size";
Console.WriteLine(System.Runtime.InteropServices.M arshal.SizeOf(t));

the result is 4, which in no way is the correct size of the object t.
