Question

    //新建cookie
    private void UserCookie(string text)
    {
        HttpCookie UserCookie = new HttpCookie("User",Server.UrlEncode("admin"));
        UserCookie.Values["User"] = text;
        Response.Cookies.Add(UserCookie);
        Response.Cookies["User"].Expires = DateTime.Now.AddDays(10);
    }
            //读取cookie
            if (IsLogin() == true)
            {
                login.Visible = false;
                TextBox1.Text =Server.UrlDecode(Request.Cookies["User"].Values["User"].ToString());
                CheckBox1.Visible = false;
            }加了Server.UrlEncode和Server.UrlDecode还是乱码？怎么改

Answer 1

HttpUtility.UrlEncode 
HttpUtility.UrlDecode编码解码，设置编码格式为utf-8string cookieName = ""; 
HttpCookie cookie = new HttpCookie(cookieName); 
cookie.Value = HttpUtility.UrlEncode("a"); 
cookie.Expires = DateTime.Now.AddDays(30); 
Response.Cookies.Add(cookie); string s= HttpUtility.UrlDecode(Request.Cookie["a"].Value); 

Answer 2

//try   
 //新建cookie
    private void UserCookie(string text)
    {
        HttpCookie UserCookie = new HttpCookie("User",Server.UrlEncode("admin"));
        UserCookie.Values["User"] = Server.UrlEncode(text); //text
        Response.Cookies.Add(UserCookie);
        Response.Cookies["User"].Expires = DateTime.Now.AddDays(10);
    }
            //读取cookie
            if (IsLogin() == true)
            {
                login.Visible = false;
                TextBox1.Text =Server.UrlDecode(Request.Cookies["User"].Values["User"].ToString());
                CheckBox1.Visible = false;
            }
