Visual Studio File Path Windows vs. Linux-CodePudding

I have some confusion about Windows path (dev machine) and Linux path (target OS for microservice)

I created a new folder in my c# project (app/yamls), put inside a file aaa.yaml and put the file in git ignore. On my windows dev machine, I see the file in c:\myproject\app\yamls. However, my microservice will run on Linux and aaa.yaml file will reside in /app/yamls.

When I run the following, I get file is missing

string file = "/app/yamls/aaa.yaml";
System.IO.File.Exists(file) // FALSE

What should be done so the new added file in visual studio will be seen as file residing in /app/yamls like it will be in production.

Thanks

You need to code file and directory handling in a cross platform manner. You could something like this: https://docs.microsoft.com/en-us/dotnet/api/System.IO.Path.PathSeparator?view=net-5.0&viewFallbackFrom=netcore-5.0

That System.IO.Path.PathSeparator will be / on Linux and \ on Windows

What I usually do is create an appsettings.json file with file location in there. And then change the config file depending on where it's deployed (Linux or Windows)

Path class has static members useful if manipulation of file paths required in .Net environment. Look at these:

Path.DirectorySeparatorChar
Path.AltDirectorySeparatorChar
Path.PathSeparator
Path.VolumeSeparatorChar

If you just need to create path from given components the Path.Combine(...) method is also useful.
