请教关于从json串取得某些行记录的问题

Question

我想从{root:
[{cpraybill_bid:'1',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'2',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'3',cpraybillid:'',vpraycode:'sdfa123123'}]
}
取出第2条第3条数据，然后在组成下面的格式
{root:
{cpraybill_bid:'2',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'3',cpraybillid:'',vpraycode:'sdfa123123'}]
}
各位帅哥、美女有现成的方法没？

Answer 1

string str = "{cpraybill_bid:'1',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'2',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'3',cpraybillid:'',vpraycode:'sdfa123123'}";        Regex rg = new Regex(@"{.*?)", RegexOptions.IgnoreCase);
        MatchCollection mc = rg.Matches(str);
        String[] results = new String[mc.Count];
        for (int i = 0; i < mc.Count; i++)
        {
            results[i] = mc[i].Value;            
        }
取2 3条

Answer 2

Regex rg = new Regex(@"{.*?)", RegexOptions.IgnoreCase);
写错了，改成 Regex rg = new Regex(@"{.*?)", RegexOptions.IgnoreCase);
results[1] results[2]即2 3 条数据

Answer 3

....
Regex rg = new Regex(@"{.*?)", RegexOptions.IgnoreCase);
写错了，改成 Regex rg = new Regex(@"\{.*?\}", RegexOptions.IgnoreCase);

Answer 4

1、你之前是个对象的格式，JSON的键也需要“”的
2、你修改之后的格式不行，没有规范的格式对应。后面那个数组去掉一个不行吗？

Answer 5

帅哥，我没用过Regex，这个是正则表达式吧，是不是得先引入个包啊？能否说的明白些？

Answer 6

var obj = {root:[{cpraybill_bid:'1',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'2',cpraybillid:'',vpraycode:'sdfa123123'},
{cpraybill_bid:'3',cpraybillid:'',vpraycode:'sdfa123123'}]};
obj["root"].splice(0, 1);
此时的obj就是去掉第一个后的结果了
