/ 04 марта 2019

У меня есть один JSON после вызова API.Я перепробовал много методов для извлечения данных из JSON и затем связал их с datagridview, но каждый раз терпел неудачу.Поэтому я хочу, чтобы кто-то помог мне с этим.У меня есть класс JSON, полученный из http://json2csharp.com

public class Attributes
{
    public string color { get; set; }
    public string finerCateg { get; set; }
    public string mainimageurl { get; set; }

    public string fuelRestriction { get; set; }
    public string hasWarranty { get; set; }
}

public class BestMarketplacePrice
{
    public double price { get; set; }
    public string sellerInfo { get; set; }
    public double standardShipRate { get; set; }
    public double twoThreeDayShippingRate { get; set; }
    public bool availableOnline { get; set; }
    public bool clearance { get; set; }

    public BestMarketplacePrice bestMarketplacePrice { get; set; }
    public List<int?> variants { get; set; }
    public bool? freight { get; set; }
}

public class RootObject
{
    public string category { get; set; }
    public string brand { get; set; }
    public string format { get; set; }
    public string nextPage { get; set; }
    public string totalPages { get; set; }
    public List<Item> items { get; set; }
}

Код десериализации: 

 List<RootObject> stores = new List<RootObject>();
RootObject ScrapedResult = JsonConvert.DeserializeObject<RootObject>(File.ReadAllText(@"D:\Test\Data1.json"));
stores.Add(ScrapedResult);
dataGridViewScrapedData.DataSource = stores;

Кроме того, что я также проверил, API успешно возвращает результат в строке"ScrapedResult"]

Результат, который я получаю в таблице данных, выглядит примерно так: enter image description here

Так что же я могу сделать, кромечто кто-то поможет мне с этим?JSON это:

Обратите внимание, что вам нужно заполнить DataSource списком объектов.В вашей строке JSON есть только один список: List<Item>.Теперь вы можете использовать этот список в качестве источника данных для вашего GridView следующим образом: 

var path = @"C:\MyStuff\json.txt";
var json = File.ReadAllText(path);
var rootObject = JsonConvert.DeserializeObject<RootObject>(json);
var items = rootObject.items;
MyGridView.DataSource = items;
// MyGridView.DataBind();

Осталось только показать первую пару свойств, а именно, category, brand, format, nextPage и totalPages.Согласно вашему JSON они кажутся исправленными, и если это так, вы можете просто показать их за пределами GridView.
