用按鈕切換列表框的可見性？

Question

可能重複：
How can I change listbox item’s visibility property in wp7?

能不能幫我切換了按鈕列表框的知名度？

這是我有：

private void button3_Click(object sender, RoutedEventArgs e) 
{ 
    listbox1.Visibility = Visibility.Visible; 
    if (listbox1.Visibility = Visibility.Collapsed) ; 
    { 
     Visibility.Visible = true; 
    } 
} 

Answer 1

這將做的工作雖然不是儘量精簡scartag的答案，Silverlight和WPF現在已經可見性屬性，已經一去不復返了使用布爾天設置可視性。

private void button3_Click(object sender, RoutedEventArgs e) 
{ 

    if (listbox1.Visibility == Visibility.Collapsed) 
    { 
     listbox1.Visibility = Visibility.Visible ; 
    } 
    else 
     listbox1.Visibility = Visibility.Collapsed; 
} 

Answer 2

private void button3_Click(object sender, RoutedEventArgs e) 
{ 
    listbox1.Visibility = listbox1.Visibility == Visibility.Visible? Visibility.Collapsed : Visibility.Visible;   
}
