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

此事件仅在用户成功验证后发生。 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 事件显示欢迎对话框。
