读取 App.config 工作正常但保存它会使应用程序崩溃

Question

我构建了一个包含 App.config 文件的应用程序，并通过安装向导项目为其创建了 Windows 安装程序。当我运行安装的应用程序时，它可以完美地读取配置，但是当我进行更改并保存配置时，应用程序就崩溃了。

这是我的代码：

Configuration applicationConfiguration = 
    ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

// Reading works just fine.
LogFilePath = applicationConfiguration.AppSettings.Settings["LogFilePath"].Value;

LogFilePath = "some string here";

applicationConfiguration.AppSettings.Settings["LogFilePath"].Value = LogFilePath;

// But saving it crashes the application. Only the .Save() line that making it crashed.
applicationConfiguration.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");

知道这里出了什么问题吗？

由于此处的文档：https://msdn.microsoft.com/en-us/library/ms134265(v=vs.110).aspx可能运行您的地图的用户具有读取权限，但没有写入权限（对文件和目录）

To get the Configuration object for a resource, your code must have read permissions on all the configuration files from which it inherits settings. To update a configuration file, your code must additionally have write permissions for both the configuration file and the directory in which it exists.
