如何从文件中读取带符号的字节 [英] How to read signed bytes from a file

问题描述

我有一个包含十六进制字的文件。

I got a file with lines of hex words.

基本上，我想将文件读入一个数组 sbyte [] 。

Basically, I want to read the file into an array sbyte[].

我知道我可以使用 byte [] >

I know probably I can read it into a byte[] using

byte[] bt = File.ReadAllBytes("fileName");

但如何将其读入带符号的字节数组？
有人可以给我一些想法吗？

But how to read it into a signed byte array? Could somebody give me some ideas?

推荐答案

文件有多大？如果它足够小， File.ReadAllBytes 没问题，你可以这样做：

How big is the file? If it is small enough that File.ReadAllBytes is fine, you can probably just do:

byte[] bt = File.ReadAllBytes("fileName");
sbyte[] sbt = new sbyte[bt.Length];
Buffer.BlockCopy(bt, 0, sbt, 0, bt.Length);

虽然坦率地说：我会把它保存为 byte [] 并担心其他地方签名/未签名。

Although frankly: I'd keep it as a byte[] and worry about signed/unsigned elsewhere.
