Question

I’m adding cookie on the server:

private void AddCookie(int id)
{
    HttpCookie cookie = new HttpCookie("wmpayment");
    cookie.Value = id.ToString();
    cookie.Expires = DateTime.Now.AddDays(2);
    this.ControllerContext.HttpContext.Response.Cookies.Add(cookie);
}

but when I am read cookie from Request – cookie.Expire equals date 01.01.0001

public static int WMPendingOrder
{
    get
    {
        var cookie = HttpContext.Current.Request.Cookies["wmpayment"];
        int id = 0;
        DateTime exp;

        if (cookie != null)
        {
            DateTime.TryParse(cookie.Expires.ToString(), out exp);
            if (DateTime.Now < exp)
                int.TryParse(cookie.Value, out id);
        }
        return id;
    }
}

log: COOKIE.Name: wmpayment COOKIE.Value: 0 COOKIE.Expire: 01.01.0001 0:00:00
I am not understand what the problem.

Answer 1

So there are basically two pieces of information you need to persist. The id and an expiry date. How about storing the expiry date in a separate cookie:

private void AddCookie(int id) 
{ 
    HttpCookie cookie = new HttpCookie("wmpayment"); 
    cookie.Value = id.ToString(); 
    cookie.Expires = DateTime.Now.AddDays(2); 
    this.ControllerContext.HttpContext.Response.Cookies.Add(cookie); 

    HttpCookie cookie = new HttpCookie("wmpaymentexpire"); 
    cookie.Value = DateTime.Now.AddDays(2).ToString(); 
    cookie.Expires = DateTime.Now.AddDays(2); 
    this.ControllerContext.HttpContext.Response.Cookies.Add(cookie); 
}

So to check the expires date for cookie wmpayment you read the value of cookie wmpaymentexpire.
