如何确定文件是否在C＃二进制或文本？ [英] How can I determine if a file is binary or text in c#?

问题描述

我需要80％，以确定是否是二进制文件或文本，有没有办法做到这一点，甚至快速和肮脏的/在C＃丑？

I need to determine in 80% if a file is binary or text, is there any way to do it even quick and dirty/ugly in c#?

推荐答案

我可能会寻找一个丰盈这将一般在一个二进制文件present但很少在一个文本文件中控制字符。二进制文件倾向于使用0，以至于只是测试了很多0字节很可能足以赶上大多数文件。如果你关心本地化你需要测试多字节模式也是如此。

I would probably look for an abundance of control characters which would typically be present in a binary file but rarely in an text file. Binary files tend to use 0 enough that just testing for many 0 bytes would probably be sufficient to catch most files. If you care about localization you'd need to test multi-byte patterns as well.

就好像说，你可以永远倒霉，并得到一个二进制文件看起来像文本，反之亦然。

As stated though, you can always be unlucky and get a binary file that looks like text or vice versa.
