在WPF中应该一次只打开一个窗口吗? [英] Only one windows should be open at once in WPF?

问题描述

我正在 vb.net 中开发一个 WPF 项目，其中有多个窗口.当用户选择一个菜单项时，会打开一个新窗口，问题是当用户单击其他菜单项时，当前窗口应该自行关闭.我如何实现它?谢谢！

推荐答案

我认为您的意思是基于您的评论:

I think you mean this based upon your comment:

Class MainWindow 

  Public Win3 As Window3 = New Window3()

  Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
    Win3.Show()
    Me.Close()
  End Sub

End Class
