我注意到在我的应用程序的user.config文件以某种方式损坏并在打开时为空的几台机器上.我似乎无法弄清楚为什么会这样.是否有一个常见的事情会导致这种情况？有什么方法可以安全地防止这个

我的第二个问题是如何恢复状态？我捕获异常并删除user.config文件,但我找不到一种方法来恢复配置而不重新启动应用程序.我在Properties对象上执行的所有操作都会导致以下错误:

"配置系统无法初始化"

重置,重新加载和升级都无法解决问题.

这是我在异常后删除的代码:

catch (System.Configuration.ConfigurationErrorsException ex)
{
    string fileName = "";
    if (!string.IsNullOrEmpty(ex.Filename))
        fileName = ex.Filename;
    else
    {
        System.Configuration.ConfigurationErrorsException innerException = ex.InnerException as System.Configuration.ConfigurationErrorsException;
        if (innerException != null && !string.IsNullOrEmpty(innerException.Filename))
            fileName = innerException.Filename;
    }
    if (System.IO.File.Exists(fileName))
        System.IO.File.Delete(fileName);
}

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