Intimate contact with asp.net (cookies)

Cookies

Cookies are also used in the same ways as the ASP. For example, we set up a cookie named ASPCN, a flying knife.

HttpCookie cookie = new httpcookie["ASPCN"];
Cookie. Value = "flying Knife";
Response.appendcookie (cookie);

It's also easy for us to remove the cookie value.

HttpCookie cookie = request.cookies["ASPCN"];
Cookievalue = cookie. Value;

Sometimes we want to store multiple messages in a cookie, and that's fine. For example, we add more information under a cookie named ASPCN.

HttpCookie cookie = new HttpCookie ("ASPCN");
Cookie. Values.add ("webmaster", "flying Knife");
Cookie. Values.add ("writer", "Beige");
Cookie. Values.add ("LinkColor", "Blue");
Response.appendcookie (cookie);

Removing information is as simple as

HttpCookie cookie = request.cookies["ASPCN"];
value1 = cookies. values["Webmaster"];
value2 = cookies. values["Writer"];

View State

This is a new thing, with the same usage and session, his main purpose is to record the state of Web control. Although it is new, but and application, the use of the session is no different, so do not want to explain in detail.

state["Droploadindex"] = 0;

Basic usage as above: But keep in mind that the information he has in existence can only be used in an ASPX file. After going out, this is no use, because his purpose is to save the state of the Web control.
