原文: WPF MVVM 关闭当前窗体 打开新的窗体

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();
}
