.net - 为什么我创建的新 WPF Windows 不是从 Window 继承的？

Question

当我创建一个新窗口时，使用 Add Item... 对话框，我创建的窗口，例如NewWindow , 不继承自 Window。它只与类型 Object 具有相同的接口(interface).一个例子:

我有下面的弹出窗口代码。代码只看到 IHavePassword成员，而不是 `LoginPopup' 的其他成员，就像它的控件一样。

Public Class LoginPopup
    Implements IHavePassword

    Public ReadOnly Property Password As SecureString Implements IHavePassword.Password
        Get
            'Return Me.PasswordBox.????
        End Get
    End Property

    Public Event PasswordChanged As RoutedEventHandler Implements IHavePassword.PasswordChanged
    Public Sub PassWordChangedHandler(sender As Object, e As EventArgs)
        PasswordChangedEvent(sender, e)
    End Sub

    Public Sub Close() Implements IHavePassword.Close
        Throw New NotImplementedException
    End Sub

End Class

哦，这也是必要的 XAML:

<Window x:Class="ApptEase.Client.Prism.Views.LoginPopup"
....
<StackPanel Orientation="Vertical" Margin="0">
    <DockPanel LastChildFill="True">
        <TextBlock Text="{Binding Path=UsernameLabel}" DockPanel.Dock="Left" TextAlignment="Right" Margin="5,9,5,5" MinWidth="70" />
        <TextBox Text="{Binding Path=Username, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True, NotifyOnValidationError=True}" Width="Auto" Margin="5" />
    </DockPanel>
    <DockPanel LastChildFill="True">
        <TextBlock Text="{Binding Path=PasswordLabel}" DockPanel.Dock="Left" TextAlignment="Right" Margin="5" MinWidth="70" />
        <PasswordBox x:Name="PasswordBox" PasswordChanged="PassWordChangedHandler" Width="Auto" Margin="5" />
    </DockPanel>
    <DockPanel LastChildFill="True" Height="59">
        <StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
            <Button Content="Log in" Command="{Binding Path=LoginCommand}" CommandParameter="{Binding ElementName=This}" Margin="5" Padding="15,10,15,10" />
            <Button Content="Cancel" Command="{Binding Path=CancelCommand}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" Margin="5" Padding="15,10,15,10"/>
        </StackPanel>
    </DockPanel>
</StackPanel>

属性 Me 上的 IntelliSense列出 IHavePassword 的成员，例如:



我希望看到控件和基础 Window这里的成员，不是界面的那些。我该如何解决这个问题？

我想你只是忘了用你的命名空间包围这个类:

Namespace ApptEase.Client.Prism.Views
    Public Class LoginPopup
        Implements IHavePassword

        '...

    End Class
End Namespace
