从JSON到Datagridview的情况下无法正常工作C＃

Question

调用API后，我有一个JSON。 我尝试了许多方法来从JSON提取数据，然后将其绑定到datagridview，但每次都失败。 所以我要有人帮我。 我有一个从http://json2csharp.com获取的JSON类

public class Attributes
{
    public string color { get; set; }
    public string finerCateg { get; set; }
    public string mainimageurl { get; set; }
    public string productTaxCode { get; set; }
    public string productUrlText { get; set; }
    public string caResidentsPropWarningRequired { get; set; }
    public string prodClassType { get; set; }
    public string canonicalUrl { get; set; }
    public string compositeWood { get; set; }
    public string numOfBatt { get; set; }
    public string actualColor { get; set; }
    public string multipackQuantity { get; set; }
    public string size { get; set; }
    public string ironBankCategory { get; set; }
    public string isSortable { get; set; }
    public string replenishmentEndDate { get; set; }
    public string features { get; set; }
    public string gender { get; set; }
    public string simsInventoryType { get; set; }
    public string isPvtLabelUnbranded { 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 class Item
{
    public int itemId { get; set; }
    public int parentItemId { get; set; }
    public string name { get; set; }
    public double msrp { get; set; }
    public double salePrice { get; set; }
    public string upc { get; set; }
    public string categoryPath { get; set; }
    public string shortDescription { get; set; }
    public string longDescription { get; set; }
    public string brandName { get; set; }
    public string thumbnailImage { get; set; }
    public string mediumImage { get; set; }
    public string largeImage { get; set; }
    public string productTrackingUrl { get; set; }
    public double standardShipRate { get; set; }
    public double twoThreeDayShippingRate { get; set; }
    public string color { get; set; }
    public bool marketplace { get; set; }
    public string modelNumber { get; set; }
    public string sellerInfo { get; set; }
    public string productUrl { get; set; }
    public string customerRating { get; set; }
    public int numReviews { get; set; }
    public string customerRatingImage { get; set; }
    public string categoryNode { get; set; }
    public string rhid { get; set; }
    public bool bundle { get; set; }
    public bool clearance { get; set; }
    public bool preOrder { get; set; }
    public string stock { get; set; }
    public Attributes attributes { get; set; }
    public string addToCartUrl { get; set; }
    public string affiliateAddToCartUrl { get; set; }
    public bool freeShippingOver35Dollars { get; set; }
    public bool availableOnline { get; set; }
    public string gender { get; set; }
    public bool? ninetySevenCentShipping { get; set; }
    public string size { get; set; }
    public bool? shipToStore { get; set; }
    public bool? freeShipToStore { 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; }
}

反序列化代码为：

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

除此之外，我还检查了API是否在字符串“ ScrapedResult”中成功返回了结果]

结果我进入datagridview只是这样的事情：

那么，除了有人帮助我之外，我还能做什么？ JSON是：

Answer 1

请注意，您需要使用对象列表填充DataSource 。 JSON字符串中只有一个列表： List<Item> 。 现在，您可以像下面这样使用此列表作为GridView的数据源：

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();

剩下的唯一事情就是显示前几个属性，即category ， brand ， format ， nextPage和totalPages 。 根据您的JSON，这些似乎是固定的，如果是这样，您可以将它们显示在GridView之外。
