C#字符串获取后如何取其中的一个字符

Question

_Callback( {"Ishost":0, "items":[], "calvisitcount":[0,19,1,10,24,11,29,1,1,2,2,2,0,4,0,1,6,2,1,0,2,2,2,0,1,3,0,0,0,1,0], "modvisitcount":[{"mod":0, "todaycount":0, "totalcount":1409245}, {"mod":1, "todaycount":0, "totalcount":0}, {"mod":3, "todaycount":0, "totalcount":10}, {"mod":8, "todaycount":0, "totalcount":98}, {"mod":10, "todaycount":0, "totalcount":17}], "lastlogin":0, "twlogincount":0, "lastgettime":1381797259});

其中我想要截取第一个"todaycount":和"totalcount":中间的那个数字该怎么截取？想了好久都没想出来，脑袋进水了。。。。。。。。。。。。。。。。。。。。。。。。因为这是从网页获取的，放在string里后不知道该怎么截取，求帮助，求思路，help。。。。。。。。。。。。。。。。。。

Answer 1

_Callback后面小括号 中的一整个字符串是一个JSON 格式的字符串。

C# 如下操作就可以了
第一步，定义类 ClassA,ClassTemp：
public class ClassA
{
public int mod;
public int todaycount;
public int totalcount;
}
public class ClassTemp
{
public int Ishost;
public int[] calvisitcount;
public ClassA[] modvisitcount;
......
}
第二步，字符串反序列化为ClassTemp：
string jsonString ={"Ishost":0, "items":[], "calvisitcount":[0,19,1,10,24,11,29,1,1,2,2,2,0,4,0,1,6,2,1,0,2,2,2,0,1,3,0,0,0,1,0], "modvisitcount":[{"mod":0, "todaycount":0, "totalcount":1409245}, {"mod":1, "todaycount":0, "totalcount":0}, {"mod":3, "todaycount":0, "totalcount":10}, {"mod":8, "todaycount":0, "totalcount":98}, {"mod":10, "todaycount":0, "totalcount":17}], "lastlogin":0, "twlogincount":0, "lastgettime":1381797259};

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
jsonString temp = serializer.Deserialize(jsonString)

temp 是一个强类型的对象了，就可以直接用了。

javascript 操作如下：
var jsonObj ={"Ishost":0, "items":[], "calvisitcount":[0,19,1,10,24,11,29,1,1,2,2,2,0,4,0,1,6,2,1,0,2,2,2,0,1,3,0,0,0,1,0], "modvisitcount":[{"mod":0, "todaycount":0, "totalcount":1409245}, {"mod":1, "todaycount":0, "totalcount":0}, {"mod":3, "todaycount":0, "totalcount":10}, {"mod":8, "todaycount":0, "totalcount":98}, {"mod":10, "todaycount":0, "totalcount":17}], "lastlogin":0, "twlogincount":0, "lastgettime":1381797259};

jsonObj 就是你要的东西了。
var todaycount= jsonObj.modvisitcount[0].todaycount;//todaycount等于 0
var totalcount= jsonObj.modvisitcount[0].totalcount;//totalcount等于 1409245
