用户信息 Froms验证票证

Froms票证是为了存储一些有用信息在客户端..一般都与Cookie一起使用..
 
//创建票证对象 
var ticket = new FormsAuthenticationTicket(1, entity.LoginName, DateTime.Now, DateTime.Now.AddMonths(1),true, entity.Id + "");
 
//根据前边的票证对象创建字符串,此字符串将用于存储进Cookie 
string encTicket = FormsAuthentication.Encrypt(ticket);
 
//根据得到的String值.存储进Cookie
var cookie = new HttpCookie(cookieName, encTicket); 
Response.Cookies.Set(cookie);
 
//从Cookie中得到前边生成的字符串并反创建出票证对象 
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(Request.Cookies[cookieName].Value);

ticket.UserData 便是前边存储的重要的验证值Ticket);
