如何猜测文件的编码，在.NET中没有BOM？ [英] How to guess the encoding of a file with no BOM in .NET?

问题描述

我使用StreamReader类在.NET这样的：

I'm using the StreamReader class in .NET like this:

using( StreamReader reader = new StreamReader( "c:\somefile.html", true ) {
    string filetext = reader.ReadToEnd();
}

这正常工作时，该文件有一个BOM。我遇到了麻烦与没有BOM的文件......基本上我胡言乱语。当我指定Encoding.Uni code它工作得很好，例如：

This works fine when the file has a BOM. I ran into trouble with a file with no BOM .. basically I got gibberish. When I specified Encoding.Unicode it worked fine, eg:

using( StreamReader reader = new StreamReader( "c:\somefile.html", Encoding.Unicode, false ) {
    string filetext = reader.ReadToEnd();
}

所以，我需要获得文件内容转换为字符串。那么，如何才能的人通常处理呢？我知道有没有解决办法，将工作时间的100％，但我想提高我的胜算..有明显的软件在那里，试图猜测（如记事本，浏览器等）。有没有在.NET框架，猜对我的方法？任何人都不会有一些code，他们想与大家分享？

So, I need to get the file contents into a string. So how do people usually handle this? I know there's no solution that will work 100% of the time, but I'd like to improve my odds .. there is obviously software out there that tries to guess (eg, notepad, browsers, etc). Is there a method in the .NET framework that will guess for me? Does anyone have some code they'd like to share?

更多背景：该<一href="http://stackoverflow.com/questions/373081/how-can-i-best-guess-the-encoding-when-the-bom-byte-order-mark-is-missing">question为pretty的多少和我一样，但我在.NET土地。这个问题使我的博客，列出各种编码检测库，但没有一个是在.NET

More background: This question is pretty much the same as mine, but I'm in .NET land. That question led me to a blog listing various encoding detection libraries, but none are in .NET
