Asp.Net MVC记住用户登录信息下次直接登录功能_实用技巧_

 //创建Cookie【防止登录信息泄露，这里使用Encode()将信息进行了加密】 SqlHelper.SetCookie("NameCookie", SqlHelper.Encode(UserName), DateTime.Now.AddDays(7)); SqlHelper.SetCookie("PwdCookie", SqlHelper.Encode(Pwd), DateTime.Now.AddDays(7)); //获取Cookie string name = SqlHelper.GetCookieValue("NameCookie"); string pwd = SqlHelper.GetCookieValue("PwdCookie"); //删除Cookie SqlHelper.RemoveCookie("NameCookie"); SqlHelper.RemoveCookie("PwdCookie"); 

 /// 
 /// 设置Cookie值和过期时间 /// 
 /// Cookie名称 /// 值 /// 过期时间 public static void SetCookie(string cookieName, string value, DateTime expires) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieName]; if (cookie != null) { cookie.Value = value; cookie.Expires = expires; HttpContext.Current.Response.Cookies.Add(cookie); } else { cookie = new HttpCookie(cookieName); cookie.Value = value; cookie.Expires = expires; HttpContext.Current.Response.Cookies.Add(cookie); } }

 /// 
 /// 获得Cookie的值 /// 
 /// Cookie名称 ///  public static string GetCookieValue(string cookieName) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieName]; if (cookie == null) return ""; else return cookie.Value; }

 　　 /// 
 /// 删除Cookie的值 /// 
 /// Cookie名称 ///  public static void RemoveCookie(string cookieName) { SetCookie(cookieName, "", DateTime.Now.AddDays(1)); }
