C#下的单一结构 [英] Single Structure under C#

问题描述

我想知道多少字节包含类型为System.Single 的值0x80000L888?

I want to know how many byte contains the value 0x80000L888 which is of type System.Single ?

推荐答案

Single始终为4个字节，无论您存储在其中的号码.

但是，您不能为其分配0x80000L888-"L"不是有效的十六进制数字！

A Single is always 4 bytes, regardless of the number you store in it.

However, you can''t assign 0x80000L888 to it - ''L'' is not a valid hex digit!

要了解您可能在下面使用的值类型的大小，

To know size of a value type you could probably use below,

static void Main(string[] args)
{
    Console.WriteLine("{0}",sizeof(Single));
}

您称单个结构为?其实是结构吗?是的，没有.所有原始类型都以其原始形式或盒装形式出现.只有盒装形式是结构.这两种形式的大小不同(盒装较大；而且，它是一类).

You call single a structure? It is a structure in fact? Yes and no. All primitive types comes in their original form or in a boxed form. Only a boxed form is a structure. These two forms have different size (boxed is larger; also, it''s a class).
