In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Form (forms) should be familiar to every WEB developer, but it is the most important source of information when a page interacts with a WEB server. Although the Asp.net WebForms framework is perfectly encapsulated to help us simplify our development work, we can manipulate those HTML form elements directly by simply using server-side controls.

For form submission, it is often used in projects, and we often get the value in the background according to the name in the form.

We receive parameters in the background:

However, when there are a lot of parameters on the page, the background will write a lot of code like this when receiving parameters:

String name=request.getParameter ("name")

Let's move on to the topic: using reflection assignment to receive parameters

Create a new User class:

Backend receiving parameters are written as follows:

This assigns the value of the form to the User class.

In addition, there are BeanUtils tools that use apache to encapsulate data (ps: this Benautils tool, which is used by the Struts framework to get form data! )
