C＃在不同页面上验证两个TextBox

Question

我有两页。第一页是注册页面，用户在该页面中创建用户名和密码。第二页是登录页面，用户在其中输入用户名和密码。我想在前端验证两者匹配。我在会话中存储了用户名和密码，而不使用数据库。这不起作用，我不确定为什么：

protected void Button1_Click(object sender, EventArgs e)
    {
        List<Information> downloadList = (List<Information>)Session["DownloadList"];
        foreach (Information obj1 in downloadList)
        {
            newName = String.Format("{0}", obj1.name);
            newPassword = String.Format("{0}", obj1.email);
        }
            if(newName != TextBoxUserNameMatch.Text)
        {
            LabelLoginError.Text = "You Must Enter the Correct User Name";
        }
            else if(newPassword != TextBoxPasswordMatch.Text)
        {
            LabelLoginError.Text = "You Must Enter the Correct Password";
        }
            else
        {
            Response.Redirect("DownloadPage.aspx");
        }

    }

谁能告诉我这里哪里出错了？这是课程信息：

public class Information
{
    public String name { get; set; }
    public String email { get; set; }
    public String phone { get; set; }
    public String zip { get; set; }
    public String state { get; set; }
    public String login { get; set; }
    public String password { get; set; }
    public String reenter { get; set; }

    public Information(String name, String email, String phone, String zip, String state, String login, String password, String reenter)
    {
        this.name = name;
        this.email = email;
        this.phone = phone;
        this.zip = zip;
        this.state = state;
        this.login = login;
        this.password = password;
        this.reenter = reenter;
    }
}

以下是我的注册页面背后的代码：

public partial class Registration : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if(!this.IsPostBack)
        {
            Information download1 = new Information("", "", "", "", "", "", "", "");

            Session["Info1"] = download1;

            DropDownListState.Items.Add(download1.name);
        }

    }

    protected void ButtonRegister_Click(object sender, EventArgs e)
    {
        String name = TextBoxName.Text;
        String email = TextBoxEmail.Text;
        String phone = TextBoxPhone.Text;
        String zip = TextBoxZip.Text;
        String state = DropDownListState.SelectedItem.Text;
        String login = TextBoxLogIn.Text;
        String password = TextBoxPassword.Text;
        String reenter = TextBoxReenter.Text;

        if(Session["DownloadList"] == null)
        {
            List<Information> downloadList = new List<Information>();
            Session["DownloadList"] = downloadList;
        }
        Information obj1 = new Information(name, email, phone, zip, state, login, password, reenter);

        List<Information> downloadList2 = (List<Information>)Session["DownloadList"];
        downloadList2.Add(obj1);
        Session["DownloadList"] = downloadList2;

        Response.Redirect("Confirmation.aspx");

我相信这些部分工作正常，因为在我的最后一页上，我打印出用户的姓名和电子邮件，而且工作正常。
