How to pass a class object from one page to another in asp.net

Question

I am developing a web application in asp.net. I am using a class with property fields to store data. And I want access that property field in another asp page without using Session . Is there any way to pass the class object from one aspx.cs page to another (like query string). When I tried to pass it through query string and when I tried to access it one another page, I got the compile time error 'cannot convert type to 'class' type' .

Answer 1

You can do it two ways:

1. Serialize the object to a string and pass it through the query string (POST body better though)
2. Serialize the object into a JSON and pass it through the POST body.

I recommend to use the second option. However, you should reconsider the question, might be, there is better approach to your root issue.

Answer 2

are you using MVC? try using TempData see the article here

or using the generic asp.net forms see this article about viewstate
