问题 Maybe it's trivial question, but I have no idea what is the type of Request.QueryString() . When I check it with typeof - it says it's Object. How to check which object it is and which property of that object is a string in URL? I'm doing it server side with language specification <%@ language="javascript"%> If I've got URL like that: http://127.0.0.1/Kamil/Default.asp?name= then how to check if name is empty? It's not null. I know I can convert Request.QueryString("name") to String and check

问题 When I try to open the page from my IDE in VS 2008 using "VIEW IN BROWSER" option I get "Object reference not set to an instance of an object" error. The piece of code I get this error : XResult = Request.QueryString["res"]; TextBox1.Text = XResult.ToString(); 回答1: The problem here is that XResult is null and when you call ToString on it the code produces a NullReferenceException . You need to account for this by doing an explicit null check TextBox1.Text = XResult == null ? String.empty :

Difference between Request.Form and Request.QueryString?

由 坚强是说给别人听的谎言 提交于 2019-12-02 23:21:25
Can some tell me the exact difference between Request.Form and Request.QueryString ? I know one difference, like If the HTTP request method is POST, the user submitted data is in the Request.Form() collection If the HTTP request method is GET, then user submitted data is in the Request.QueryString() collection any other difference? and Any example would be greatly appreciated. In Request.Form the data is posted in http header whereas in QueryString data is sent through url. I found some other difference Request("id") will first try to locate Request.Form("id") then Request.Querystring("id")

Why is Request.QueryString readonly?

I thought you couldn't change the QueryString on the server without a redirect. But this code works* for me: Request.QueryString edit I'm so amazed. So here are my questions regarding this: Why is Request.QueryString readonly? Why does this code/hack work*? How safe is it, if you change to readonly as soon as you are done editing, both regarding bad errors or unexpected behaviour, and regarding maintaining and understanding the code? Where in the event cycle would it make most sense to do this crazy edit if you are only using PageLoad and OnPageRender? *More details: I have a page with items
