新 Windows C# 构建导致应用丢失已保存的首选项

Question

每次我重新编译 Windows 应用程序时，我都会更新 AssemblyInfo.cs 中的 AssemblyVersion 和 AssemblyFileVersion。

当我的应用程序加载时，我调用

Microsoft.Win32.RegistryKey key1 = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Classes\MyFileType\shell\open\command", true);
           if (key1 == null)
           {
                Registry.SetValue(@"HKEY_CURRENT_USER\Software\Classes\MyFileType\shell\open\command", null, "\"" + Application.ExecutablePath + "\"" + " \"%1\"");
                flag = true;
            }
            Microsoft.Win32.RegistryKey key2 = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Classes\.abc", true);
            if (key2 == null)
            {
                Registry.SetValue(@"HKEY_CURRENT_USER\Software\Classes\.abc", null, "MyFileType");
                flag = true;
            }
            Microsoft.Win32.RegistryKey key3 = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Classes\MyFileType\DefaultIcon", true);
            if (key3 == null)
            {
                   Registry.SetValue(@"HKEY_CURRENT_USER\Software\Classes\MyFileType\DefaultIcon", "", Application.ExecutablePath + ",2");
                   flag = true;
            }
if (flag) SHChangeNotify(0x08000000, 0x0000, (IntPtr)null, (IntPtr)null);//SHCNE_ASSOCCHANGED SHCNF_IDLIST

每次我新编译的应用程序运行时，所有保存的首选项都消失了，应用程序恢复为默认首选项。

知道是什么触发了应用程序失去它的首选项吗？是不是因为我更新了版本号？如果是这样，我该如何解决？

是否因为我重新插入了注册表项？

会是什么？

首选项在应用程序运行的实例之间正常加载和保存，直到我进行新的构建...但这里是代码：

 private void SaveSettings()
    {
        Properties.Settings.Default.useLastB = this.lastB.Checked;
        Properties.Settings.Default.useLast2B = this.last2B.Checked;
        Properties.Settings.Default.useLast3B = this.last3B.Checked;
        Properties.Settings.Default.useLastSV = this.lastSV.Checked;
        Properties.Settings.Default.useLast2SV = this.last2SV.Checked;
        Properties.Settings.Default.useLast3SV = this.last3SV.Checked;
        Properties.Settings.Default.showAverage = this.averageBox.Checked;
        Properties.Settings.Default.showSum = this.sumBox.Checked;
        Properties.Settings.Default.showNormalized = this.normalBox.Checked;
        Properties.Settings.Default.pessimistic = this.pessimistic.Checked;
        Properties.Settings.Default.realistic = this.realistic.Checked;
        Properties.Settings.Default.optimistic = this.optimistic.Checked;
        Properties.Settings.Default.useAinsley = this.ainsleyBox.Checked;
        Properties.Settings.Default.useHandicapper = this.handicapperBox.Checked;
        Properties.Settings.Default.useCustom = this.customBox.Checked;
        Properties.Settings.Default.UseMorningLine = this.useMLBox.Checked;
        Properties.Settings.Default.SolveAllRacesToSingleFile = this.singleFileCheckBox.Checked;

        Properties.Settings.Default.Save();
    }

    private void LoadSettings()
    {
        Properties.Settings.Default.Reload();
        this.lastB.Checked = Properties.Settings.Default.useLastB;
        this.last2B.Checked = Properties.Settings.Default.useLast2B;
        this.last3B.Checked = Properties.Settings.Default.useLast3B;
        this.lastSV.Checked = Properties.Settings.Default.useLastSV;
        this.last2SV.Checked = Properties.Settings.Default.useLast2SV;
        this.last3SV.Checked = Properties.Settings.Default.useLast3SV;
        this.averageBox.Checked = Properties.Settings.Default.showAverage;
        this.sumBox.Checked = Properties.Settings.Default.showSum;
        this.normalBox.Checked = Properties.Settings.Default.showNormalized;
        this.pessimistic.Checked = Properties.Settings.Default.pessimistic;
        this.realistic.Checked = Properties.Settings.Default.realistic;
        this.optimistic.Checked = Properties.Settings.Default.optimistic;
        this.handicapperBox.Checked = Properties.Settings.Default.useHandicapper;
        this.ainsleyBox.Checked = Properties.Settings.Default.useAinsley;
        this.customBox.Checked = Properties.Settings.Default.useCustom;
        this.useMLBox.Checked = Properties.Settings.Default.UseMorningLine;
        this.singleFileCheckBox.Checked = Properties.Settings.Default.SolveAllRacesToSingleFile;
    }

谢谢

应用程序设置的默认位置是这个路径：

%USERPROFILE%\Local Settings\Application Data\<Company Name>\<appdomainname>_<eid>_<hash>\<verison>\user.config

请注意，版本是路径的一部分 - 这就是为什么当您增加版本号时，应用程序似乎已丢失其设置。

您可以覆盖它的存储位置以消除对路径中版本的依赖 - 请参阅 Application Settings Architecture
