c# - 调用 MakeRequest 方法时，我的 MVC 未显示正确的视图

Question

我有以下课程：

public class Product
{
        [JsonProperty("image")]
        public string ImageURL { get; set; }
        [JsonProperty("superDepartment")]
        public string SuperDepartment { get; set; }
        [JsonProperty("tpnb")]
        public long TPNB { get; set; }
        [JsonProperty("ContentsMeasureType")]
        public string ContentsMeasureType { get; set; }
        [JsonProperty("name")]
        public string Name { get; set; }
        [JsonProperty("UnitOfSale")]
        public int UnitOfSale { get; set; }
        [JsonProperty("description")]
        public IEnumerator<string> LstDescription { get; set; }
        public string Description { get; set; }
        [JsonProperty("AverageSellingUnitWeight")]
        public decimal AverageSellingUnitWeight { get; set; }
        [JsonProperty("UnitQuantity")]
        public string UnitQuantity { get; set; }
        [JsonProperty("id")]
        public long ID { get; set; }
        [JsonProperty("ContentsQuantity")]
        public int ContentsQuantity { get; set; }
        [JsonProperty("department")]
        public string Department { get; set; }
        [JsonProperty("price")]
        public decimal Price { get; set; }
        [JsonProperty("unitprice")]
        public decimal UnitPrice { get; set; }
    }

我在productController上有方法：

    public async Task<ActionResult> MakeRequest(string q)// worked 
    {
        var client = new HttpClient();
        client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "56ac439a92694577a2779f3d0ee0cd85");

        var uri = string.Format("https://dev.tescolabs.com/grocery/products/?query={0}&offset={1}&limit={2}", q, 0, 10);

        var response = await client.GetAsync(uri);          
        string body = await response.Content.ReadAsStringAsync();
        Product myoutput = JsonConvert.DeserializeObject<Product>(body);
        }
        return View(body);
    }

我有下面的模型：

出于某种原因，当我调用该方法时MakeRequest，它仅将信息显示为字符串，并显示如下图所示服务器错误的错误，我们可以从 api 中看到信息，但它显示为字符串。 错误消息 来自 api 的信息应该显示在下表中： table

如何在表格中显示数据？或者更好的如何将 json 数组转换为 net 对象？

我知道我的方法下面的部分缺少一些东西：

Product myoutput = JsonConvert.DeserializeObject<Product>(body);

我用简单的方式告诉你。

你的 json 模型

-uk --ghs ---产品 ----结果

{
  "uk" : {
    "ghs" : {

如果你看上面的 json 结果，你需要一个更全面的模型。

为此，您可以在此处将 json 结果输入模型。看这里

或使用动态保持结果对象的当前状态。

   string body = response.Content.ReadAsStringAsync().Result;

            dynamic content = JObject.Parse(body);

            var products = content.uk.ghs.products.results;
