我们在读取标准 .Net 用户设置时发生了一个罕见的异常(这是在 VS 2008 的“项目属性”中找到的设置):

InnerException:
*注意:这是从测试应用程序重新创建的。
我调出 user.config 文件,其中一半丢失了。
我希望我们的应用程序由于某种原因突然终止。
这似乎非常罕见,这是我们与设置交互的方式:
//How we read
Settings settings = Settings.Default;
_ourStaticMemberVariable = settings.OurValue;
//How we save
Settings settings = Settings.Default;
settings.OurValue = "Our Value";
settings.Save();
我们使用它的方式有什么问题吗?两个调用都有一个 try-catch 来放置一些默认值,但是这些值需要能够从我们的应用程序中重置。
在这种状态下,我们的应用程序无法保存新设置——而且我想不出一种以编程方式恢复的好方法。我不得不手动找到 user.config 并将其删除。
我也尝试调用 Settings.Reset() 等,但得到相同的异常。
有想法该怎么解决这个吗?还是我们最好编写自己的设置系统或以其他方式保存持久设置?
编辑:如果您收到 ConfigurationErrorsException,解决方法是从代码中删除文件。
有人知道如何获取 user.config 文件的完整路径吗?
