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

问题描述

我在.NET中使用StreamReader类，如下所示：

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

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

当文件有一个BOM时，这个工作正常。我遇到了一个没有BOM的文件的麻烦，基本上我有乱码当我指定Encoding.Unicode它工作正常，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();
}

文件内容到一个字符串，所以人们通常如何处理这个？我知道有没有解决方案，将工作100％的时间，但我想提高我的赔率..有明显的软件在那里试图猜测例如，记事本，浏览器等）。在.NET框架中有一个方法来猜测我吗？任何人都有一些代码，他们想分享？

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：此与我的很相似，但我在.NET的土地。这个问题让我看到一个博客列出了各种编码检测库，但没有.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
