登录成功窗体切换

1、xaml

点击事件将登录页面某个控件带回至ViewModel

<Button Content="登  录" Command="{Binding LoginCommand}" CommandParameter="{Binding ElementName=pb_password}" Margin="30,10" Width="286" Height="40" Style="{StaticResource ButtonPrimary}"/>

2、viewmodel

/// <summary>



        /// 登录事件




        /// </summary>




        public RelayCommand<System.Windows.Controls.PasswordBox> LoginCommand =>



            new Lazy<RelayCommand<System.Windows.Controls.PasswordBox>>(() =>



                new RelayCommand<System.Windows.Controls.PasswordBox>(Login)).Value;

private void Login(System.Windows.Controls.PasswordBox password)



{



    WIndex window = new WIndex();



                        window.Show();







                        Window.GetWindow(password).Close();



}
