显示 VB.NET WPF 窗口

Display VB.NET WPF window

提问by ApplePie

Sorry for this extremely amateur question, but I cannot make this work. I want to make a custom font dialog window (just for the heck of learning how it would be done) and from what I have found using Google, I should create an instance of the window I want to show and then call the Show() or ShowDialog() methods. However the intellisense popup does not show such methods as available and indeed the code does not compile and complains that those methods don't exist. Is there something really simple I am missing or am I just way off ?

很抱歉这个非常业余的问题，但我无法完成这项工作。我想创建一个自定义字体对话框窗口（只是为了学习如何完成），并且根据我使用 Google 的发现，我应该创建一个我想要显示的窗口实例，然后调用 Show()或 ShowDialog() 方法。然而，智能感知弹出窗口并未显示可用的此类方法，并且代码确实无法编译并抱怨这些方法不存在。是否有一些非常简单的东西我错过了或者我只是离开了？

Imports System.IO

Class MainWindow
    Public font_dialog As Window1 = New Window1

    // ... Removed code that was not pertinent

    Private Sub menu_font_Click(sender As System.Object, e As _
        System.Windows.RoutedEventArgs) Handles menu_font.Click
        // does not compile
        font_dialog.Show()
    End Sub
End Class

Here is the exact error message:

这是确切的错误消息：

Error 1 'Show' is not a member of 'WpfApplication1.Window1'. C:\Users\notmyrealusername\documents\visual studio 2010\Projects\WpfApplication2\WpfApplication2\MainWindow.xaml.vb 24 9 WpfApplication2

错误 1“显示”不是“WpfApplication1.Window1”的成员。C:\Users\notmyrealusername\documents\visual studio 2010\Projects\WpfApplication2\WpfApplication2\MainWindow.xaml.vb 24 9 WpfApplication2

XAML for Window1:

'Show' is not a member of 'WpfApplication1.Window1'.

“显示”不是“WpfApplication1.Window1”的成员。

That mans your Window1is not a (valid) Window ...

那芒你Window1不是一个（有效的）窗口......

Post the first lines of the XAML and the code behind.

发布 XAML 的第一行和后面的代码。

Also, you probably want to call ShowDialog(), but that is a separate issue.

此外，您可能想调用 ShowDialog()，但这是一个单独的问题。

You must make Window1 inherit from Window, which has the Show method. In Visual Studio, you can right click the project you want to add the window to and click Add -> Window.

您必须使 Window1 继承自具有 Show 方法的Window。在 Visual Studio 中，您可以右键单击要添加窗口的项目，然后单击“添加”->“窗口”。
