Question

我在加载CheckBox的保存设置时遇到问题（Checked True或False）。在调用已保存的设置时，它总是从IsolatedStorage天气返回True，CheckBox是否已被检查？请看附带的代码，如果有人能告诉我我的方式错误，我将不胜感激。

亲切的问候

将

    Private Sub Button2_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button2.Click

'Rem Save Settings'

如果CheckBox1.IsChecked = True则

IsolatedStorageSettings.ApplicationSettings（“MyCheckBox”）= CheckBox1.IsChecked = True

ElseIf CheckBox1.IsChecked = False然后

IsolatedStorageSettings.ApplicationSettings（“MyCheckBox”）= CheckBox1.IsChecked = False

结束如果

End Sub

    Private Sub Button3_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button3.Click

'Rem调用已保存的设置'

MessageBox.Show（“首先选择坦克程序”）

CheckBox1.IsChecked =（IsolatedStorageSettings.ApplicationSettings（“MyCheckBox”））

End Sub

本回答是由来自Microsoft Silverlight Forunm的Karmjit Singh向我提供的

Private Sub Button1_Click（sender As System.Object，e As System.Windows.RoutedEventArgs）处理Button1.Click

  If IsolatedStorageSettings.ApplicationSettings.Contains("MyCheckSettings") Then
     IsolatedStorageSettings.ApplicationSettings("MyCheckSettings") = CheckBox1.IsChecked
  Else
     IsolatedStorageSettings.ApplicationSettings.Add("MyCheckSettings", CheckBox1.IsChecked)
  End If

End Sub

Private Sub Button2_Click（sender As System.Object，e As System.Windows.RoutedEventArgs）处理Button2.Click

  Dim x As Boolean?

  IsolatedStorageSettings.ApplicationSettings.TryGetValue(Of Boolean?)("MyCheckSettings", x)
  CheckBox2.IsChecked = x

End Sub

使用IsolatedStorage保存CheckBox（vb）
