问题：
What I want to achieve is very simple: I have a Windows Forms (.NET 3.5) application that uses a path for reading information. 我想要实现的非常简单：我有一个Windows Forms（.NET 3.5）应用程序，该应用程序使用读取信息的路径。 This path can be modified by the user, by using the options form I provide. 用户可以使用我提供的选项表单来修改此路径。
Now, I want to save the path value to a file for later use. 现在，我想将路径值保存到文件中以备后用。 This would be one of the many settings saved to this file. 这将是保存到该文件的众多设置之一。 This file would sit directly in the application folder. 该文件将直接位于应用程序文件夹中。
I understand three options are available: 我了解三个选项可供选择：
- ConfigurationSettings file (appname.exe.config) ConfigurationSettings文件（appname.exe.config）
- Registry 登记处
- Custom XML file 自定义XML文件
I read that the .NET configuration file is not foreseen for saving values back to it. 我读到没有预见到.NET配置文件来将值保存回它。 As for the registry, I would like to get as far away from it as possible. 至于注册表，我想尽可能地远离它。
Does this mean that I should use a custom XML file to save configuration settings? 这是否意味着我应该使用自定义XML文件保存配置设置？ If so, I would like to see code example of that (C#). 如果是这样，我想查看该代码示例（C＃）。
I have seen other discussions on this subject, but it is still not clear to me. 我已经看到了有关该主题的其他讨论，但是对我来说仍然不清楚。
