從Request.form獲取嵌套值

Question

我正在嘗試從在C＃Webforms中使用“ POST”方法接收的數據中提取一些值，示例數據為：

{  
   "ProductStockDetailsID":8015425,
   "LocationID":24213,
   "ProductID":19284305,
   "MinStock":null,
   "MaxStock":null,
   "OnOrder":0,
   "Alerts":false,
   "ProductStocks":[  
    {  
     "StockID":11839663,
     "CurrentStock":68,
     "CurrentVolume":0,
     "CreatedDate":"2019-06-30T09:58:38.4",
     "DeletedDate":null,
     "CostPrice":0.00000,
     "ProductStockDetailsID":8015425
    }
   ]
}

我使用Request.Form["ProductID"]成功提取了ProductID ，但是我無法提取CurrentStock值，因為它看起來是嵌套在ProductStocks 。

為什么不為請求定義類，然后僅解析請求。 為此，您需要覆蓋ProcessRequest方法，例如

 public override void ProcessRequest(HttpContext context) { string json; using (var reader = new StreamReader(context.Request.InputStream)) { json = reader.ReadToEnd(); } var data = JsonConvert.DeserializeObject<RequestData>(json); base.ProcessRequest(context); ProcessRequest(data); } private void ProcessRequest(RequestData data) { // ... your code } 

而要解析的類是：

 public class RequestData { public int ProductStockDetailsID { get; set; } public int LocationID { get; set; } public int ProductID { get; set; } public object MinStock { get; set; } public object MaxStock { get; set; } public int OnOrder { get; set; } public bool Alerts { get; set; } public Productstock[] ProductStocks { get; set; } } public class Productstock { public int StockID { get; set; } public int CurrentStock { get; set; } public int CurrentVolume { get; set; } public DateTime CreatedDate { get; set; } public object DeletedDate { get; set; } public float CostPrice { get; set; } public int ProductStockDetailsID { get; set; } } 

現在只使用data.ProductStocks
