Request,request.params,request.querystring,request.form in C #

If you want to pass data on two pages, you can only use Request.QueryString, Request.Form, Request.Cookies

Request.params is looking for data in QueryString, Form, Server Variable, and Cookies, he first looks up data in the QueryString collection, and returns data if the data is found in QueryString, To find the data in the Form collection if it is not found, return it, or find the data in the next collection.

request.params["id"], repuest["id"
request.querystring["id"]
What is the use and difference of request.form["id"?
Request.params is a collection of all post and get-pass values, Request.Form is a post-pass value, and Request.QueryString is a get-pass-along value

When I looked at this question, I saw that there was an interesting question asked. He asked whose value the request.params["id", request["id" was taken if post and get or even cookies passed the value of the ID's parameter. If you look at it carefully, you should understand. The request is to sequentially query the values in these collections if this is already present in the previous set, he will return this value. You will not be able to inquire whether or not he is behind you.

What are the usages and differences between request.params["id", request.form["id", and request.querystring["id"?

Request.params is a collection of all post and get-pass values, Request.Form is a post-pass value, and Request.QueryString is a get-pass-along value
