C＃ – 用户设置已损坏

在阅读标准.Net用户设置时，我们遇到了罕见的exception（这是VS 2008中“项目属性”中的设置）：

*注意：这是从测试应用程序重新创建的。

我拉起了user.config文件，其中一半丢失了。

我希望我们的申请因某种原因而突然终止。

这似乎非常罕见，这是我们如何与设置进行交互：

 //How we read Settings settings = Settings.Default; _ourStaticMemberVariable = settings.OurValue; //How we save Settings settings = Settings.Default; settings.OurValue = "Our Value"; settings.Save(); 

我们如何使用它有什么问题吗？ 两个调用都有一个try-catch，它放置了一些默认值，但是这些值需要能够从我们的应用程序重置。

在这种状态下，我们的应用程序无法保存新设置 – 我无法找到以编程方式恢复的好方法。 我不得不手动找到user.config并删除它。

我也尝试调用Settings.Reset（）等，但获得相同的exception。

有想法该怎么解决这个吗？ 或者我们最好是编写自己的设置系统还是以其他方式保存持久性设置？

编辑：解决方法是从代码中删除文件，如果您得到ConfigurationErrorsException。

任何人都知道如何获取user.config文件的完整路径？

  public static bool CheckSettings() { var isReset = false; try { ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal); } catch (ConfigurationErrorsException ex) { string filename = string.Empty; if (!string.IsNullOrEmpty(ex.Filename)) { filename = ex.Filename; } else { var innerEx = ex.InnerException as ConfigurationErrorsException; if (innerEx != null && !string.IsNullOrEmpty(innerEx.Filename)) { filename = innerEx.Filename; } } if (!string.IsNullOrEmpty(filename)) { if (System.IO.File.Exists(filename)) { var fileInfo = new System.IO.FileInfo(filename); var watcher = new System.IO.FileSystemWatcher(fileInfo.Directory.FullName, fileInfo.Name); System.IO.File.Delete(filename); isReset = true; if (System.IO.File.Exists(filename)) { watcher.WaitForChanged(System.IO.WatcherChangeTypes.Deleted); } } } } return isReset; } 

 [STAThread] private static void Main(string[] args) { try { // ... } catch (System.Configuration.ConfigurationErrorsException ex) { var config = ((System.Configuration.ConfigurationErrorsException)ex.InnerException).Filename; // notify user, ask them to restart System.IO.File.Delete(config); Application.Exit(); } }
