我最近将我游戏的启动器重新制作为WPF。虽然大部分代码都运行良好，但是当我移动它时，我正在处理的一个特殊功能完全破坏了。
我正在处理的功能是一个简单的备份系统。设置很简单：用户转到保存管理器并勾选自动备份设置。这是tick的XAML代码：
<CheckBox x:Name="AutoBackupCheckbox" Content="{x:Static properties1:Resources.EnableBackupsString}" HorizontalAlignment="Left" Margin="0,10,0,0" VerticalAlignment="Top" Checked="AutoBackupCheckbox_CheckChanged" Unchecked="AutoBackupCheckbox_CheckChanged" IsChecked="{Binding Source={x:Static properties1:Settings.Default},Path=AutoBackupEnabled}"/>
当复选框上的勾号发生变化时，会发生这种情况：
private void AutoBackupCheckbox_CheckChanged(object sender, RoutedEventArgs e)
{
Settings.Default.AutoBackupEnabled = AutoBackupCheckbox.IsEnabled;
MessageBox.Show(Settings.Default.AutoBackupEnabled.ToString());
Settings.Default.Save();
}
问题是代码坚定地坚持True。我不知道是什么迫使这个设置。这使得备份系统始终被禁用，因为在调试期间，我总是看到设置在为真时返回false。
以下是启动器在启动时所执行的操作的代码：

var jumperDeck = new JumpList();
jumperDeck.JumpItems.Add(JumperCatalog.StartGameJumpTask);
jumperDeck.JumpItems.Add(JumperCatalog.QuickLoadJumpTask);

}
_gameProcess.StartInfo = GameInfo;
if (Settings.Default.AutoBackupEnabled && Settings.Default.AutoBackupLocation != null)
BackupEngine.MonitorSetupCode();
_gameProcess.Start();
_gameProcess.WaitForExit();
if (Settings.Default.AutoBackupEnabled && Settings.Default.AutoBackupLocation != null &&
BackupEngine.CountChanges > 0 &&
!Settings.Default.SingleBackupMode) BackupEngine.SnapshotBackupCode();
else if (Settings.Default.AutoBackupEnabled && Settings.Default.AutoBackupLocation != null &&

使用IsEnabled，而不是IsEnabled！ {{1}}始终为true，因为它仅检查是否启用了复选框。如果用户选中复选框，则必须使用IsChecked属性。
文档：ToggleButton.IsChecked

我发现了这个问题。还有另一个组件一直发送true（和false），因为该组件上的数据绑定是TwoWay，而不是OneWay。这一点，以及迈克的解决方案解决了这个问题。
