访问特殊文件夹中的App.exe.config文件 [英] Accessing App.exe.config File in Special Folders

问题描述

全部，我通常在使用

Properties.Settings.Default.SomeSetting = someVal;
Properties.Settings.Default.Save();

我被要求在安装之间保持设置，并且有两条路线；切换到使用注册表，或将.config文件保存到在两次安装之间保留的单独的特殊文件夹（由于设置数量，我选择了后者）。

I have been asked to persist settings between installations and there are two routes; switch to using the registry, or save the .config file to a separate Special Folder that is persisted between installations (I have chosen the later due to number of settings).

我的.config文件被写入一个奇数目录，即

My .config gets written to an odd directory, namely

C:\Users\Administrator\AppData\Local\MyApp\
    MyApp.vshost.exe_Url_mzfwtdo5po4pcuabybebhsn5yfltbb3w\1.0.0.0

我的问题是：如何在C＃中选择此目录？

注意：我已经尝试过

string appPath = Application.ExecutablePath;
Configuration config = ConfigurationManager.OpenExeConfiguration(appPath);
string strIPACostConfigFile = config.FilePath;

这是在安装目录中给我的初始.config文件。

Which gives me the initial .config in the installation directory.

谢谢您的时间。

推荐答案

您不必知道配置文件的位置。您只需要默认为 true 的设置，并在程序启动时调用以下调用即可。

You don't have to know the location of your config file. You just need a Setting that is true by default and call the following call when your programm starts.

if (Settings.Default.IsUpgrade)
{
  Settings.Default.Upgrade();
  Settings.Default.IsUpgrade = false;
  Settings.Default.Save();
}

这样，早期版本中的设置将被迁移到新版本中

That way, settings made in an earlier version will be migrated to the new one.
