抓取下来的数据，该怎么样处理？
试了下带\u的都是Unicode,我用 HttpUtility.HtmlDecode(str)转换不成功，原来是什么样结果还是什么样。怎么样才能把下面代码中的Unicode转成汉字?

[解决办法]
HttpUtility.HtmlDecode(str,Encoding.Uncode)//试试这样写，反正就这样的格式，怎么搞自己从写下吧
[解决办法]
测试：
string sadf = "var data = {\"abstract\":{\"show\":\"\",\"all\":\"\"},\"content\":{\"show\":\"<\\/a>"
+ "\u7b2c\u4e09\u4e2a"
+ "\"},\"mediafeedback\":{\"show\":\"\"},\"extract\":{\"show\":\"\",\"all\":\"\"}}; var no_txt = \""
+ "\u672c\u5546\u54c1\u6682\u65e0\u8be6\u60c5\u3002<\\/p>\"; ";
输出结果：
var data = {"abstract":{"show":"","all":""},"content":{"show":"<\/a>第三个"},"mediafeedback":{"show":""},"extract":{"show":"","all":""}}; var no_txt = "本商品暂无详情。<\/p>";
[解决办法]
原因在于你获取的时候用的是Encoding.Default，肯定不是Encoding.Unicode，缺省可能是UTF8吧，所以获取来的数据里，\u523b\u5256被当作普通英文和数字，也就是说，\u没有被视作转义字符。
而string testb = "\u523b\u5256"里，\u被认出是转义字符，所以中文会正确显示。
解决方法（参考了stackoverflow: http://stackoverflow.com/questions/1615559/converting-unicode-strings-to-escaped-ascii-string):
string test1 = Regex.Replace(myReader.ReadToEnd(), @"\\u(?<Value>[a-zA-Z0-9]{4})", m => { return ((char)int.Parse(m.Groups["Value"].Value, System.Globalization.NumberStyles.HexNumber)).ToString();});
