c# - 从 Request.form 获取嵌套值

问题描述

我正在尝试从使用 c# webforms 中的“POST”方法收到的数据中提取一些值，示例数据是：

{  
   "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
    }
   ]
}

我用来成功Request.Form["ProductID"]提取ProductID，但我无法提取CurrentStock值，因为它看起来是从ProductStocks.

解决方案

为什么不为请求定义类，然后只解析请求。为此，您需要覆盖 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 
 }

要解析的类是：

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; }
}

现在只需使用data.ProductStocks
