我正在制作一个带有身份验证服务的 Silverlight 4.0 导航应用程序来管理用户、登录/注销等。
我在此页面上使用了 msdn 教程：http: //msdn.microsoft.com/en-us/library/ee942451%28v=vs.91%29.aspx
它工作得很好。我可以创建具有一些自定义配置文件属性的用户并登录和注销。
问题是我创建用户表单。与教程一样，我在我的服务项目中创建了一个名为 NewUser 的类，带有数据注释。这些似乎有效，就好像我尝试使用无效字段创建用户一样，创建失败，并且出现异常，并显示存在验证错误的消息。
我希望此验证适用于我的表单。在其他表单中，我只是将一个类的实例绑定到表单并将每个字段的绑定设置为validationOnException 为true 和notifyOnValidationError 为true。
我已经在创建用户表单中进行了绑定，就像在我的其他表单中一样，但它们似乎不起作用。我试图在 NewUser 类的一组属性中设置断点。看起来它根本没有被调用/使用。
这很可能是我遗漏了什么的简单问题，但我不知道是什么。这是否与 NewUser 类在我的服务项目中并且表单在客户端项目中的事实有关。我希望你们能帮助我。
我的 NewUser 类代码
public class NewUser
{
private string username;
[Key]
[Required()]
public string UserName { get; set; }
[Key]
[Required()]
[RegularExpression(@"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", ErrorMessage="Invalid email. An email must use the format username@mycompany.com")]
public string Email { get; set; }
[Required()]
public string Firstname { get; set; }
[Required()]
public string Lastname { get; set; }
[Required()]
public DateTime Birthsday { get; set; }
[Required()]
public bool SentNewsletter { get; set; }
[Required()]
public bool SentReminders { get; set; }
[Required()]
public string Password { get; set; }
[CustomValidation(typeof(RegistrationValidator), "IsPasswordConfirmed")]
public string ConfirmPassword { get; set; }
[Required()]
public string SecurityQuestion { get; set; }
[Required()]
public string SecurityAnswer { get; set; }
}
我创建用户表单 xaml

我在后面创建用户表单代码
public partial class CreateNewUser : Page
{
private NewUser user;
public CreateNewUser()
{
InitializeComponent();
user = new NewUser();
LayoutRoot.DataContext = user;
dpBirthsday.SelectedDate = DateTime.Now;
cboxNewsletter.IsChecked = true;
cboxReminders.IsChecked = true;
}
private void btnCreate_Click(object sender, RoutedEventArgs e)
{
updateValidation();
if (!Validation.GetHasError(LayoutRoot))
{
RegistrationDomainContext context = new RegistrationDomainContext();
NewUser user = new NewUser();
try
{
user.UserName = txtUsername.Text;
user.Password = txtPassword.Password;
user.Email = txtEmail.Text;
user.ConfirmPassword = txtPassword.Password;
user.SecurityQuestion = txtPasswordQuestion.Text;
user.SecurityAnswer = txtPasswordAnswer.Text;
user.Firstname = txtFirstname.Text;
user.Lastname = txtLastname.Text;
user.Birthsday = dpBirthsday.SelectedDate.GetValueOrDefault(DateTime.Now);
user.SentNewsletter = cboxNewsletter.IsChecked.GetValueOrDefault(true);
user.SentReminders = cboxReminders.IsChecked.GetValueOrDefault(true);
context.NewUsers.Add(user);
context.SubmitChanges(RegisterUser_Completed, null);
}
catch (Exception exc)
{
ErrorWindow w = new ErrorWindow(exc);
w.Show();
}
} // end validation
}
private void RegisterUser_Completed(SubmitOperation so)
{
if (so.HasError)
{
ErrorWindow ew = new ErrorWindow(so.Error);
ew.Show();
so.MarkErrorAsHandled();
}
else
{
LoginParameters lp = new LoginParameters(txtUsername.Text, txtPassword.Password);
}
}
private void btnCancel_Click(object sender, RoutedEventArgs e)
{
MainPage mp = Application.Current.RootVisual as MainPage;
mp.contentFrame.Navigate(new Uri("/home", UriKind.Relative));
}
private void updateValidation()
{
foreach (var current in LayoutRoot.Children)
{
if (current is TextBox)
(current as TextBox).GetBindingExpression(TextBox.TextProperty).UpdateSource();
if (current is PasswordBox)
(current as PasswordBox).GetBindingExpression(PasswordBox.PasswordProperty).UpdateSource();
}
}
}
