獲取查詢字符串變量webrequested

Question

我編程方式創建這樣

 string url = "http://aksphases:201/min-konto/printpdf.aspx?id=149656222&name=Ink%20And%20Toner"; 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
     request.CookieContainer = new CookieContainer(); // required for HttpWebResponse.Cookies 
     request.Method = "POST"; 
     request.ContentType = "application/x-www-form-urlencoded"; 
     byte[] data = Encoding.UTF8.GetBytes("email=mymail&password=1234"); 
     request.ContentLength = data.Length; 
     using (Stream stream = request.GetRequestStream()) 
     { 
      stream.Write(data, 0, data.Length); 
     } 
     HttpWebResponse myWebResponse = (HttpWebResponse)request.GetResponse(); 
     Stream ReceiveStream = myWebResponse.GetResponseStream(); 

一個Web請求，並在printpdf.aspx頁面（你可以看到它的網址）我想要得到的查詢字符串參數，當這個URL以編程方式執行時。當我嘗試平常的方式

HttpContext.Current.Request.QueryString["id"] 

它不起作用。 有什麼我在做錯誤的方式。還是有沒有更好的方法來做到這一點？

究竟在Web應用程序中，你在調用它？

HttpContext.Current.Request.QueryString["id"] 

這裏就是我想你應該嘗試： 在您的客戶端應用程序：

string url = "http://aksphases:201/min-konto/printpdf.aspx?id=149656222&name=Ink%20And%20Toner"; 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 

    // try this 
    Debug.WriteLine("About to send request with query=\"{0}\"", request.RequestUri.Query); 
    // and check to see what gets printed in the debug output windows 

    request.CookieContainer = new CookieContainer(); // required for HttpWebResponse.Cookies 
    request.Method = "POST"; 
    request.ContentType = "application/x-www-form-urlencoded"; 
    byte[] data = Encoding.UTF8.GetBytes("email=mymail&password=1234"); 
    request.ContentLength = data.Length; 

，而在你的ASPX頁面，試試這個：

protected void Page_Load(object sender, EventArgs e) { 
     var theUrl = this.Request.Url.ToString(); 
     Debug.WriteLine(theUrl); // is this the exact URL that you initially requested ? 
     // if you have FormsAuthentication or other redirects 
     // this might get modified if you're not careful 

     var theId = this.Request.QueryString["id"]; 
     Debug.WriteLine(theId); 
    }
