正如你所看到的，身体是一切是非常重要的，身体是完全转义JSON字符串。在C＃中，有没有什么好的方法来使用这个完全转义的JSON字符串？
这是来自Facebook的一个例子（拉动喜欢的人和来自帖子的评论，对我的Feed有最多评论的帖子是政治性的，所以对数据的无知感到抱歉...）和你可以看到，Unicode的字符转换为\\u0031式的，引号的样子\\\"，新线看起来像\\n等
还有一些逃脱的转义字符，例如在体内的意见之一具有\\\\"因为它是逃逸的char（如果这是有道理的话）。
如果这些可以转换为其正常的JSON解析他们的非转义的甲酸，这将是最好的。
谢谢！

有评论recommedning使用Regex.Unescape（）。
我使用.NET 4.5，此方法不会使用unescape \ n和\“ 您可能会阅读HttpWebResponse或类似的响应，您可能希望将其响应流转换为字节数组，然后播放一下将其转换为字符串
这就是我目前使用的库，如何使用它将字符串转换为我想要的那样？ – 2011-06-02 21:45:24
您首先解析文档并获取正文字符串。然后把它放到解析器中 – CodesInChaos 2011-06-02 21:53:48
我明白了，你是对的，但是我在找的是'Regex.Unescape（）'方法，我得到了一个解析异常，因为所有的特殊字符仍然是逃过一劫。 – 2011-06-02 22:21:09
