ClientFormsAuthenticationMembershipProvider.UserValidated 事件
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
在用户通过验证后发生。
public:
event EventHandler<System::Web::ClientServices::Providers::UserValidatedEventArgs ^> ^ UserValidated;public event EventHandler<System.Web.ClientServices.Providers.UserValidatedEventArgs> UserValidated;member this.UserValidated : EventHandler<System.Web.ClientServices.Providers.UserValidatedEventArgs> Public Custom Event UserValidated As EventHandler(Of UserValidatedEventArgs) Public Event UserValidated As EventHandler(Of UserValidatedEventArgs) 事件类型
示例
以下示例代码演示如何使用此事件在窗体的标题栏中显示用户名。
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
注解
仅当用户成功验证后，才会发生此事件。 可以使用此事件更新应用程序以反映当前用户。 例如，可以使用 UserValidatedEventArgs.UserName 属性在应用程序用户界面 (UI) 中显示用户名。
可以通过调用 ClientFormsIdentity.RevalidateUser 方法以无提示方式重新验证用户。 因此，应避免使用 UserValidated 事件来显示侵入性 UI。 例如，不应使用 UserValidated 事件来显示欢迎对话框。
