这是我在阅读博客文章后做的..但我没有得到任何输出..
this i made after reading blog posts.. but i am not getting any output..
所以PLZ帮助我。
推荐答案
我曾经使用过这种反序列化JSON对象的方法，但这只适用于这种类型的JSON对象，在其他情况下它失败。
I used to use this kind of methods to Deserialize a JSON object, but this works in just this type of JSON Objects, in other cases it fails.
所以我建议你使用一个更通用的术语，它将在大多数情况下工作案件。
So I would suggest you using a more general term which will work in most of the cases.
它的工作原理如下：
string s = streamReader.ReadToEnd();
Dictionary< string，List< Dictionary< string，object>>> jsonObj =
Dictionary<string, List<Dictionary<string, object>>> jsonObj =
<跨度类= "x_Apple标签跨度" 样式= "空白：预"> JsonConvert.DeserializeObject<字典<字符串列表与LT;字典<串，对象> >>>（s）;
JsonConvert.DeserializeObject<Dictionary<string, List<Dictionary<string, object>>>>(s);
现在，您可以按照常用的方式遍历字典。
Now you can iterate through the Dictionary like you are always used to.
JsonConvert是来自Newtonsoft.Json命名空间的第三方类：http：//james.newtonking.com/pages/json-net.aspx
JsonConvert is a third-party class from Newtonsoft.Json namespace found here: http://james.newtonking.com/pages/json-net.aspx
将对象序列化回JSON再次就像这个一样简单。希望它有所帮助
Serializing the object back to JSON is again as easy as this one. Hope it helps
