在 C# 中解析 Cryptocompare API Json 数据

Question

我正在从 https://min-api.cryptocompare.com/data/histominute?fsym=BTC&tsym=ETH&limit=30&aggregate=1&e=CCCAGG

加载数据

这是return:

我想用 c# 解析数据。主要对每个 'data' 列表条目（时间、高、低……）做一些事情有什么建议吗？

编辑：

我安装了这个 json 包。这是代码。

    string url_kraken = @"https://min-api.cryptocompare.com/data/histominute?fsym=ETH&tsym=EUR&limit=2000&aggregate=15&e=Kraken&extraParams=yeahnoworries";
var client_kraken = new WebClient();
var content_kraken = client_kraken.DownloadString(url_kraken);
var results_kraken = JsonConvert.DeserializeObject<List<CoinMarketCap_API_JSON>>(content_kraken);

Answer 1

只需使用 Json.Net:

https://www.nuget.org/packages/Newtonsoft.Json/

要使用 nuget 安装它，请在程序包控制台中使用以下命令：

Install-Package Newtonsoft.Json

如果您有 json 可以映射到的特定 class（例如 JsonMapClass），您可以像这样使用它：

JsonMapClass json = JsonConvert.DeserializeObject<JsonMapClass>(jsonstring);

否则你可以使用动态对象：

dynamic jsonjson = JsonConvert.DeserializeObject(jsonstring);

Answer 2

创建两个对象。例如：

First:
public class JsonData {
public string time {get; set;}
public string high {get; set;}
etc...
}

Second:
public class DataRoot {
public string Response {get; set:}
public string Type {get; set:}
public bool Aggregated{get; set:}
public List<JsonData> Data{get; set:}
}

var root = JsonConvert.DeserializeObject<DataRoot>(YOUR JSON STRING HERE);
var rootData = root.Data;

完成...
