C＃在应用程序配置文件中设置appdata或任何特殊文件夹路径

Question

I was trying to find a way to use appdata path as my environment.currentdurectory which means I want to run the c# application from appdata folder and in my project I always used environment.currentdirectory.

I couldn't find a way that I can set appdata path in app config and later replace environment.curentdirectory by appdata path...

PS:.

1) I want to set my programs data path as appdata

2) my project code is set to use environment.currentdirectory

3) I don't want to replace environment.currentdirectory by going each line by line

Have you tried doing this via the app domain.

See:

https://docs.microsoft.com/en-us/dotnet/api/system.appdomain.basedirectory?view=netframework-4.7.2

    // Create application domain setup information
    var domaininfo = new AppDomainSetup();
    domaininfo.ConfigurationFile = System.Environment.CurrentDirectory + 
                                   Path.DirectorySeparatorChar +
                                   "ADSetup.exe.config";
    domaininfo.ApplicationBase = System.Environment.CurrentDirectory;

    //Create evidence for the new appdomain from evidence of the current application domain
    Evidence adEvidence = AppDomain.CurrentDomain.Evidence;

    // Create appdomain
    AppDomain domain = AppDomain.CreateDomain("Domain2", adEvidence, domaininfo);

    // Display application domain information.
    Console.WriteLine("Host domain: " + AppDomain.CurrentDomain.FriendlyName);
    Console.WriteLine("Child domain: " + domain.FriendlyName);
    Console.WriteLine();
    Console.WriteLine("Configuration file: " + domain.SetupInformation.ConfigurationFile);
    Console.WriteLine("Application Base Directory: " + domain.BaseDirectory);

    AppDomain.Unload(domain);

So, I found that we can not get app data path from the config file directly unless we set any.

The best use se would be just get the app data path by

Environment.specialfolder method and use that.

Otherwise the answer posted above is given by MSDN itself and obviously works but too large code
