问题描述

What's wrong with my classes?.我的课怎么了？ I see array of objects as response:我将对象数组视为响应：

private void btSubmit_Click(object sender, EventArgs e)
{
    string myJsonResponse = "";
    string uri = "https://api-mainnet.rarible.com/items/0xb32979486938aa9694bfc898f35dbed459f44424%3A2/ownerships";
    
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
    
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        using (Stream stream = response.GetResponseStream())
            using (StreamReader reader = new StreamReader(stream))
            {
                myJsonResponse = reader.ReadToEnd();
            }
    
    lista_root myDeserializedClass = JsonConvert.DeserializeObject<lista_root>(myJsonResponse);
    
    string ab = "1";
}
    
public class Root
{
    public string id { get; set; }
    public string token { get; set; }
    public string tokenId { get; set; }
    public string owner { get; set; }
    public int value { get; set; }
    public DateTime date { get; set; }
    public string status { get; set; }
    public int selling { get; set; }
    public int sold { get; set; }
    public int stock { get; set; }
    public List<object> pending { get; set; }
    public bool blacklisted { get; set; }
    public string creator { get; set; }
    public bool verified { get; set; }
    public List<object> categories { get; set; }
    public int likes { get; set; }
    public bool hide { get; set; }
    public int? price { get; set; }
    public int? priceEth { get; set; }
    public string buyToken { get; set; }
    public string buyTokenId { get; set; }
    public string signature { get; set; }
}
            
public class lista_root
{
    public List<Root> data { get; set; }
}

This json node contains something similar to this:此 json 节点包含与此类似的内容：

My goal here is to deserialize the object and loop through it.我的目标是反序列化 object 并循环遍历它。

I assume that you:我假设你：

  • Try to deserialize JSON array;尝试反序列化 JSON 数组；
  • using dotnet 5 / using System.Text.Json;使用 dotnet 5 / 使用 System.Text.Json；

you can easily deserialize JSON array with您可以轻松地反序列化 JSON 阵列

List<Root> roots = JsonSerializer.Deserialize<List<Root>>(json);
