读写和删cookies，网上搜索了一段代码，求调用的代码

Question

老大们，我想读写和删cookies，网上搜索了一段代码，却死活不会用（基础太差了，初学。。不好意思）。
能不能请你写出来调用的代码呀？
谢谢！
    public void WriteCookies(HttpResponse response, HttpRequest request, HttpServerUtility server, string IndexValue,
                             string TextValue, int ExpriesHour)
    {
        response.Cookies[IndexValue].Value = TextValue;
        response.Cookies[IndexValue].Expires = DateTime.Now.AddHours(ExpriesHour);
    }    public string ReadCookies(HttpResponse response, HttpRequest request, HttpServerUtility server, string IndexValue)
    {
        if (request.Cookies[IndexValue] != null)
            return request.Cookies[IndexValue].Value;
        return "";
    }    public void DeleteCookies(HttpResponse response, HttpRequest request, HttpServerUtility server, string IndexValue)
    {
        if (request.Cookies[IndexValue] != null)
        {
            HttpCookie cookies = request.Cookies[IndexValue];
            cookies.Expires = DateTime.Now.AddHours(-1);
            response.Cookies.Add(cookies);
        }
    }

Answer 1

System.Web.HttpCookie newcookie = new HttpCookie("user");
newcookie.Values["username"] = "";
newcookie.Values["password"] = "";
newcookie.Expires = DateTime.Now.AddDays(15);
Response.AppendCookie(newcookie);
System.Web.HttpCookie cookie = Request.Cookies["user"];
if (cookie != null)
{
cookie.Expires = DateTime.Now.AddDays(-1);
Response.Cookies.Set(cookie);
}HttpCookie cookie = System.Web.HttpContext.Current.Request.Cookies[cookiename];  
if (cookie != null)  
{  
cookie.Values.Clear();  
SetUserCookieExpireTime(cookiename, -1);  
cookie.Domain = _domain;  
System.Web.HttpContext.Current.Response.Cookies.Set(cookie);  
}  
public static void SetUserCookieExpireTime(string key, int days)  
{  
System.Web.HttpContext.Current.Response.Cookies[key].Domain = _domain;  
System.Web.HttpContext.Current.Response.Cookies[key].Path = _cookiepath;  
System.Web.HttpContext.Current.Response.Cookies[key].Expires = DateTime.Now.AddDays(days);  
}
