[.net] Retrieve a cookie from the harddrive, C#
Author
I'm currently writing an application which is supposed to get some data from a webpage. In order to do that I want to use a cookie which is saved on the harddrive. Is it possible to load a cookie which is stored from the harddrive, or do I have to create them myself? The c#-pseuode code below should explain what i want..
You have to make a persistent cookie, so you have to set an expiration date. If you do not do that, it will automatically become a temporary cookie.
Create like this:
HttpCookie objCookie = new HttpCookie("MyCookie");DateTime now = DateTime.Now;//The following code adds a pair of keys and values:objCookie.Values.Add("Time", now.ToString());objCookie.Values.Add("ForeColor", "White");objCookie.Values.Add("BackColor", "Blue");//The following code sets the expiration time of the cookie to one hour:objCookie.Expires = now.AddHours(1)Response.Cookies.Add(objCookie);And retrieve the cookie like this:
HttpCookie objCookie = Request.Cookies["myCookie"];lblTime.Text = objCookie.Values["Time"];lblTime.BackColor = System.Drawing.Color.FromName(objCookie.Values["BackColor"]);Hope this helps,

Thanx the help! Unfortunately it doesn't help since i'm not coding a webpage. If I'm not misstaken the Request object is only a part ASP.NET.
