如何获得字符串中的字节数 [英] How do you get the number of bytes in a string

问题描述

问候，


什么是返回字符串中字节数的C＃代码，如

32313131353131333432317E547E3132357E5553447E467E35 36363031303030343835323632
7E307E56


我认为应该是80.

谢谢

Greetings,

What is the C# code that returns the number of bytes in a string such as

32313131353131333432317E547E3132357E5553447E467E35 36363031303030343835323632
7E307E56

It should be 80 I think.
thanks

推荐答案

好​​吧，没有什么可以返回字节数，但是

String.Length会返回字符数。

char是unicode，这是16位，所以字符串至少是
160字节（实际上我算了83个字符，所以166+字节）

Well, there is nothing that would return the number of bytes, but
String.Length would return the number of characters.
A char would be unicode, which is 16 bits, so the string would be at least
160 bytes (actually I counted 83 characters, so 166+ bytes)

Morten，

谢谢

我害怕我想要一个sizeof。


packet.length返回162，所以我猜我们为''x0减去2 '结束

字符串给160和160/2给我们80字节，这是规格说的

字节数是。


这看起来是否正确。

Morten,
thanks
I was afraid of that I would like a "sizeof".

The packet.length return 162, so I guess we subtract 2 for the ''x0'' end of
string giving 160 and 160 / 2 gives us 80 bytes which is what the specs say
the number of bytes is.

Does this seem correct.

有一个sizeof运算符，但我认为这只会显示

类/结构大小。

sizeof（String）;

此外，sizeof仅适用于''不安全''代码块。

There is a sizeof operator but I think that would only show you the
class/structure size.
sizeof(String);
Also, sizeof only works with the ''unsafe'' code blocks.
