Question

我正在使用Json.net，这是我的json：

{
    "miner": "t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF",
    "totalHash": 1523943880.832757,
    "totalShares": 4089.53223605,
    "networkSols": "7644579",
    "immature": 0.29784511,
    "balance": 0,
    "paid": 1092.22974323,
    "workers": {
        "t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF": {
            "name": "t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF",
            "diff": 54500,
            "shares": 106.44625040000004,
            "invalidshares": 0,
            "currRoundShares": 4082.8793454,
            "currRoundTime": 0,
            "hashrate": 1523943880.832757,
            "hashrateString": "3.05 KSol/s",
            "luckDays": "5.574",
            "luckHours": "133.768",
            "paid": 1092.22974323,
            "balance": 0
        }
    },
    "history": {
        "t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF": [
            {
                "time": 1516522247,
                "hashrate": 1600923951.4915187
            },
            {
                "time": 1516526867,
                "hashrate": 1523943880.832757
            }
        ]
    }
}

我想在内部获取元素hashrateString＆＃34; workers＆＃34;在里面＆＃34; t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF＆＃34;但是＆＃34; t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF＆＃34;每次都会改变。

这是我目前的代码：

String dl = webClient.DownloadString("http://hushpool.cloud/api/worker_stats?t1biSMuXyq5eKkP8zDPViKHF9mbS9ZFLRuF");
JObject json = JObject.Parse(dl);
JObject workers = JObject.Parse(JObject.Parse(dl).SelectToken("workers").First.ToString());
label7.Text = (String)json.GetValue("balance");
label8.Text = (String)json.GetValue("pending");
label9.Text = (String)json.GetValue("paid");
label10.Text = (String)workers.GetValue("hashrateString");

我尝试了不同的代码，但没有任何效果。你能帮助我吗？

Answer 1

由于minerValue不是常量，因此您需要首先从json获取它并使用它遍历JObject以获取hashrateString的值

JObject obj = JObject.Parse(json);
JObject workers = (JObject)obj.GetValue("workers");
string minerValue = obj.GetValue("miner").ToString();
JObject minerWorker = (JObject)workers.GetValue(minerValue);
string hashRate = minerWorker.GetValue("hashrateString").ToString();

更新：根据您的评论，如果存在属性名称略有不同的场景，您可以使用以下代码来获取对象：

JObject workerMiner = (JObject)workers.Properties().FirstOrDefault(p => p.Name.StartsWith(minerValue)).Value;

请记住，此代码不是生产就绪，因为您需要处理角落/故障情况（例如，json中不存在 worker 或 miner 属性）

Answer 2

这是使用jsonpath从json文本中检索'hashratestring'的另一种方法。

JObject obj = JObject.Parse(jsonTxt);
string name = (string)obj.SelectToken("$.workers.*.hashrateString");
Console.WriteLine(name);

输出：

3.05 KSol/s
