C# json解析

json格式数

[{
    "id": ,
    "docentry": ,
    "pmid": ,
    "ItemCode": "UBAC11211OF-A54",
    "basicName_bg": "男女式涤纶挎包",
    "taxDate": "2018-07-24 10:37:20"
}, {
    "id": ,
    "docentry": ,
    "pmid": ,
    "ItemCode": "UBAC11711OF-A54",
    "basicName_bg": "男女式收纳袋",
    "taxDate": "2018-07-24 10:37:20"
}, {
    "id": ,
    "docentry": ,
    "pmid": ,
    "ItemCode": "UBAC05811OF-A40",
    "basicName_bg": "男女式涤纶背包",
    "taxDate": "2018-07-24 10:37:20"
}]

用JArray

JArray aa = JArray.Parse(json);
        for (int i = ; i < aa.Count; i++)
        {
            string docentry = aa[i]["id"].ToString();
        }

还有一种方法是拼接json

{
    "d": [{
        "id": ,
        "docentry": ,
        "pmid": ,
        "ItemCode": "UBAC11211OF-A54",
        "basicName_bg": "男女式涤纶挎包",
        "taxDate": "2018-07-24 10:37:20"
    }, {
        "id": ,
        "docentry": ,
        "pmid": ,
        "ItemCode": "UBAC11711OF-A54",
        "basicName_bg": "男女式收纳袋",
        "taxDate": "2018-07-24 10:37:20"
    }, {
        "id": ,
        "docentry": ,
        "pmid": ,
        "ItemCode": "UBAC05811OF-A40",
        "basicName_bg": "男女式涤纶背包",
        "taxDate": "2018-07-24 10:37:20"
    }]
}

JObject jsonObj = new JObject();

        string json = context.Request["data"];

        string json_str = "{\"d\":" + json + "}";
        jsonObj = JObject.Parse(json_str);
        foreach (var item in jsonObj["d"])
        {
            string docentry = item["id"].ToString();
        }

        JArray aa = JArray.Parse(json);
        for (int i = ; i < aa.Count; i++)
        {
            string docentry = aa[i]["id"].ToString();
        }
