请问asp.net如何读取加密COOKIE
我的登陆页是这样的，我想在用户登陆后在每个页面显示用户名，请问如何从COOKIE中读出来啊，谢谢
protected void Enter_Click(object sender, EventArgs e)ASP.NET 加密 Cookie
{
FormsAuthentication.Initialize();
string name = Request.Form["name"].Trim();
string pwd = Request.Form["pwd"].Trim();
string yanzheng = Request.Form["yanzheng"].Trim();
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString());
conn.Open();
string sql = "select count(*) from userinfo where username='" + name + "' and userpwd='" + pwd + "'";
SqlCommand cmd = new SqlCommand(sql, conn);
int count = Convert.ToInt32(cmd.ExecuteScalar());
if (string.Compare(Request.Cookies["CheckCode"].Value, yanzheng, true) != 0)
{
Response.Write("<script>alert('验证码输入不正确');location.href='../admin/login.aspx';</script>");
Response.End();
}
else
{
if (count > 0)
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,name,DateTime.Now,DateTime.Now.AddMinutes(30),true,//Roles,//用户所属的角色字符串
FormsAuthentication.FormsCookiePath);
//加密身份验证票据
string hash = FormsAuthentication.Encrypt(ticket);
//创建要发送到客户端的cookie
HttpCookie mycookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash);
if (ticket.IsPersistent)
{
mycookie.Expires = ticket.Expiration;
}
//把准备好的cookie加入到响应流中
Response.Cookies.Add(mycookie);
//转发到请求的页面
Response.Redirect(FormsAuthentication.GetRedirectUrl(name, false));
}
else
{
Response.Write("<script>alert('用户名密码不正确');location.href='../admin/login.aspx';</script>");
}
}
}
