我想读取并解析我的有效 JSON 文件。但可能是我在加载时做错了什么，因此没有得到有效的文件

我有一个包含有效 JSON 数据的 json 文件。但是当我使用以下方法加载它时：

 (StreamReader r = new StreamReader(filePath))
   {
     string json = r.ReadToEnd();
   }

我得到了这样的东西：

{\n \"item\": [\n  {\n   \"name\": \"Infinix smart 3 PLUS - 6.2\\\"water drop Display - Triple Rear Camera - 32GB ROM,2GB RAM-Fingerprint sensor-Face unlock\",\n   \"url\": \"https://www.daraz.pk/products/infinix-smart-3-plus-62water-drop-display-triple-rear-camera-32gb-rom-2gb-ram-20ghz-quadcore-processor-i113246358-s1264944281.html?search=1\",\n   \"price\": \"Rs. 17,999\",\n   \"Image\": \"https://static-01.daraz.pk/p/2066cca3b8cf77faa08eaeedfbe69b12.jpg_340x340q80.jpg\",\n   \"Detail\": \"Specifications of Infinix smart 3 PLUS - 6.2\\\"water drop Display - Triple Rear Camera - 32GB ROM,2GB RAM-Fingerprint sensor-Face unlock\\nBrand Infinix SKU 113246358_PK-1264944281 Model Smart 3 Plus\\nWhat’s in the box1xmobile with accessories\\nVIEW MORE\"\n  },\n  {\n   \"name\": \"Honor 7C - 5.99\\\" FHD Display - 3GB RAM - 32GB ROM - Fingerprint Sensor & Face Unlock\",\n   \"url\": \"https://www.daraz.pk/products/honor-7c-599-fhd-display-3gb-ram-32gb-rom-fingerprint-sensor-face-unlock-i3287863-s12693427.html?search=1\",\n   \"price\": \"Rs. 18,999\",\n   \"Image\": \"https://static- .........

现在我用它来解析数据

    var jobj = JObject.Parse(json);

所以我得到了这种结果：

    {
     "item": [

但上面加载的 json 文件从来没有给我结果。我什至尝试过这个来解析我的模型，但它总是给我null：

var someType = JsonConvert.DeserializeObject<RootObj>(jobj.ToString());

当我检查这个在线 JSON 验证器时： https ://jsonlint.com/ 我发现我在 json 文件的开头和结尾得到了双括号（“{{”和“}}”）。这是无效的，必须删除。我的问题是我在哪里做错了为什么在开始和结束时使用双花括号，尽管我的 json 文件都是正确的。

编辑：我已经更新了我的完整 json 文件，结果是双括号。而原始数据的开头和结尾都有 1 个花括号。

    using (StreamReader r = new StreamReader(icon_path))
    {
        string json = r.ReadToEnd();
        var jobj = JObject.Parse(json);
        List<ObjectList> items = 
   JsonConvert.DeserializeObject<List<ObjectList>>(jobj.ToString());


     }

以上是在我的模型中解析我的数据的完整行

这是我的模型课

 public class ObjectList
    {
        public string name { get; set; }
        public string url { get; set; }
        public string price { get; set; }
        public string Image { get; set; }
        public string Detail { get; set; }

     }

这是我一直在寻找的解决方案。谢谢大家的回答。

string jsonetext = File.ReadAllText(icon_path);
Items items = JsonConvert.DeserializeObject<Items>(jsonetext);

我已经更新了我的模型类如下：

public class Daraz
{
    public string name { get; set; }
    public string url { get; set; }
    public string price { get; set; }
    public string Image { get; set; }
    public string Detail { get; set; }

}

public class Items
{
    public List<Daraz> Item { get; set; }
}
