从Request.form获取嵌套值

Question

I'm trying to extract some values from data I received using "POST" method in c# webforms, sample data is:

{  
   "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
    }
   ]
}

I use Request.Form["ProductID"] to extract the ProductID successfully, But I'm not able to extract the CurrentStock values because it looks to be nested from ProductStocks .

Why not define the class for request and then just parse the request. TO do this you need to override ProcessRequest method like

 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 } 

And the class to parse is:

 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; } } 

Now just use data.ProductStocks
