c#如何解析json？

Question

{"retcode":0,"result":[{"poll_type":"message","value":{"msg_id":32065,"from_uin":2246865592,"to_uin":1589188359,"msg_id2":605408,"msg_type":9,"reply_ip":178848417,"time":1352614319,"content":[["font",{"size":10,"color":"000000","style":[0,0,0],"name":"\u9ED1\u4F53"}],"hi"]}}]}请问如何用Newtonsoft.Json或其他类库取出hi这个值，感激不尽！

usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
usingNewtonsoft.Json;
usingNewtonsoft.Json.Converters;
usingNewtonsoft.Json.Serialization;
usingNewtonsoft.Json.Linq;
namespacecscliTest
{
publicclassFont
{
publicintsize;
publicintcolor;
publicstringname;
publicListstyle=newList();
}
publicclassContent
{
publicstringhi;
publicFontfont=newFont();
}
publicclassValue
{
publicintmsg_id;
publicuintfrom_uin;
publicuintto_uin;
publicintmsg_id2;
publicintmsg_type;
publicintreply_ip;
publicinttime;
publicListcontent=newList();
}
publicclassResult
{
publicstringpoll_type;
publicValuevalue;
}
publicclasssss
{
publicintretcode;
publicListresult=newList();
}
publicclassTest
{
publicintm_a;
publicinta
{
get;
set;
}
}
classProgram
{
staticvoidMain(string[]args)
{
//测试数据
sssa=newsss();
a.retcode=0;
Resultr=newResult();
Valuev=newValue();
Contentc=newContent();
Fontf=newFont();
f.size=10;
f.color=0;
f.style=newList(newint[]{0,0,0});
f.name="xxx";
c.font=f;
c.hi="hello";
v.msg_id=32065;
v.from_uin=2246865592;
v.to_uin=1589188359;
v.msg_id2=605408;
v.msg_type=9;
v.reply_ip=178848417;
v.time=1352614319;
v.content.Add(c);
r.value=v;
a.result.Add(r);
stringxx=JsonConvert.SerializeObject(a);
Console.WriteLine(xx);
//方法一（需定义上面那些类）
sssa2=(sss)JsonConvert.DeserializeObject(xx);
Console.WriteLine(a2.retcode);
//方法二（不需定义上面那些类）
JObjecto=(JObject)JsonConvert.DeserializeObject(xx);
JTokeno2=o["result"][0];
JTokeno3=o2["value"];
JTokeno4=o3["content"][0];
JTokeno5=o4["hi"];
Console.WriteLine(o5.ToString());
}
}
}感觉content后面的两个[[格式有问题，所以我这里的和你的格式有点差别，请注意。
以前做过，今天翻了下，网上的太乱，以至于弄了挺久。

varser=newJavaScriptSerializer();
returnser.Deserialize(json);JavaScriptSerializer类在System.Web.Script.Serialization需引入System.Web.Extensionsdll
