AWS EC2讀取商品文件JSON文件

Question

我正在嘗試解析AWS EC2讀取商品文件JSON文件，但在讀取文件時遇到問題。 正如您在JSON文件中看到的那樣，這里有一個產品列表，並且JSON文件的鍵值每次都不同，我無法讀取它。 任何想法如何讀取文件？

每當遇到具有結構良好值的變量鍵時Dictionary<string, ...>可以使用Dictionary<string, ...> ：

var obj = JsonConvert.DeserializeObject<RootObject>(json);
foreach (var offer in obj.Reserved.Values.SelectMany(v => v.Values))
{
    Console.WriteLine(offer.effectiveDate);
    foreach (var priceDim in offer.priceDimensions.Values)
        Console.WriteLine("\t" + priceDim.description);
}

// .....................

public class RootObject
{
    public Dictionary<string, Dictionary<string, Offer>> Reserved { get; set; }
}

public class Offer
{
    public string offerTermCode { get; set; }
    public string sku { get; set; }
    public DateTime effectiveDate { get; set; }
    public Dictionary<string, PriceDimension> priceDimensions { get; set; }
    public TermAttributes termAttributes { get; set; }
}

public class PriceDimension
{
    public string rateCode { get; set; }
    public string description { get; set; }
    public string beginRange { get; set; }
    public string endRange { get; set; }
    public string unit { get; set; }
    public Dictionary<string, string> pricePerUnit { get; set; }
    public object[] appliesTo { get; set; }
}

public class TermAttributes
{
    public string LeaseContractLength { get; set; }
    public string OfferingClass { get; set; }
    public string PurchaseOption { get; set; }
}

注意我假設您使用JSON.Net在C＃中處理JSON。
