範例

下列範例程式碼示範如何使用這個事件，在表單的標題列中顯示使用者名稱。

private ClientFormsAuthenticationMembershipProvider formsMembershipProvider =
    (ClientFormsAuthenticationMembershipProvider)
    System.Web.Security.Membership.Provider;
private String appName = "ClientAppServicesDemo";

private void AttachUserValidatedEventHandler()
{
    formsMembershipProvider.UserValidated += 
        new EventHandler<UserValidatedEventArgs>(Form1_UserValidated);
}

private void Form1_UserValidated(object sender, UserValidatedEventArgs e)
{
    // Set the form's title bar to the application name and the user name.
    this.Text = String.Format("{0} ({1})", appName, e.UserName);
}

Private WithEvents formsMembershipProvider As  _
    ClientFormsAuthenticationMembershipProvider = _
    System.Web.Security.Membership.Provider

Private appName As String = "ClientAppServicesDemo"

Private Sub Form1_UserValidated(ByVal sender As Object, _
    ByVal e As UserValidatedEventArgs) _
    Handles formsMembershipProvider.UserValidated

    ' Set the form's title bar to the application name and the user name.
    Me.Text = String.Format("{0} ({1})", appName, e.UserName)

End Sub

備註

只有在成功驗證使用者之後，才會發生此事件。 您可以使用此事件來更新應用程式，以反映目前的使用者。 例如，您可以使用 UserValidatedEventArgs.UserName 屬性，在應用程式使用者介面中顯示使用者名稱， (UI) 。

您可以呼叫 ClientFormsIdentity.RevalidateUser 方法，以無訊息方式重新驗證使用者。 因此，您應該避免使用 UserValidated 事件來顯示干擾 UI。 例如，您不應該使用 UserValidated 事件來顯示歡迎對話方塊。
