------解决方案--------------------
  string sh = HttpUtility.UrlEncodeUnicode("京东商城").Replace(@"%u",@"\u");

------解决方案--------------------
输出结果没有问题啊
\u4eac\u4e1c\u5546\u57ce

探讨


引用:
用一下我写的

不行，也是\\U
我其实是在输出一个unicode的json格式字符串

现在客户端收到的是 
{"errno":"0","data":{"resource_detail":{"id":"129","name":"\\u4eac\\u4e1c\\u5546\\u57ce","res_type":"1"}}}

而期……

示例代码：
C# code
var source = "京东商城";
var result = source.Aggregate(string.Empty,
                                                 (current, c) => current + string.Format("{0}{1:x4}", @"\u", (int) c));

Console.WriteLine(result);
