c# 将二进制数据读取到字符串中
我已经看过很多如何将字节数组转换为字符串的示例，但是当我开始使用加密时，这给我带来了许多问题。出于好奇，有人知道直接将二进制数据读取到字符串上的方法吗？
执行此操作的 VB6 方法是：
Dim S as string
s = space$(lof(1))
Get #1,, s
close #1
如果没有，我已经看到了将字符串转换为字节数组、返回字符串（包括 base64、UTF8）的不同方法，最后 - 逐个字符并将其转换为字节。
我的目标很简单。我想将二进制数据检索到字符串中，加密该字符串，最后将所有字符串数据写回到新的二进制文件中。
您认为哪种方法是最快的方法？
I have seen plenty of examples of how to convert a byte array into a string, but this is causing me many problems down the road when I start to work with encryption. Just out of curiosity, does anyone know of a method to read binary data straight onto a string.
The VB6 method of doing this would be:
Dim S as string
s = space$(lof(1))
Get #1,, s
close #1
If not, I have seen different ways of converting string to byte array, back to string including base64, UTF8, and lastly - going through char by char and converting it into a byte.
My goal is simple. I want to retrieve binary data onto a string, encrypt this string, and lastly write all of the strings data back into a new binary file.
Which method would you say is the fastest way of doing this?

如果您只想加密二进制数据，那么您应该完全避免使用字符串。如果您正在加密属于字符串中的文本信息，那么您应该关心编码（UTF-8 和类似的编码） - 尽管读取数据、将其放入字符串、加密字符串然后写出数据似乎是一个奇怪的要求。
If you simply want to encrypt binary data then you should avoid using a string altogether. If you are encrypting textual information that belongs in a string then you should be caring about encodings (UTF-8 and friends) - although reading in data, putting it into a string, encrypting the string and then writing out data seems an odd requirement.
您声明要从
byte[]到string再到byte[]；首先，请注意编码（例如UTF-8）不是一个选项；仅当将字符串转换为二进制再返回字符串时才适用。区别很重要：它实际上需要是文本数据才能工作，并且任意byte[]不能被视为文本数据。出于类似的原因（不限于：代理等），这也排除了您的“直接写入字符串”。将二进制编码为字符串的正确方法是使用 base-64、base-16 等； base-64 是这里最有效的通用编码。
然而;大多数加密代码适用于二进制，而不是文本。如果您有文本加密 API，在大多数情况下，它要做的第一件事就是使用 UTF-8 等编码将其转换为二进制。
所以：检查您是否缺少直接二进制 API 选项。
You state that you want to go from
byte[]tostringtobyte[]; firstly, note thatEncoding(such as UTF-8) is not an option; that only applies when going string to binary back to string. The difference is important: it needs to actually be textual data for that to work, and an arbitrarybyte[]can not be treated as textual data. This also rules out your "direct write into a string", for similar reasons (not limited to: surrogates etc).The correct way to encode binary to a string is with base-64, base-16, etc; base-64 is the most efficient general purpose encoding here.
However; most encryption code works with binary, not text. If you have a text encryption API, in most cases the first thing it is going to do is to turn it into binary using an encoding such as UTF-8.
So: check you aren't missing a direct binary API option.
