[c#] File path for project files?

I am working on a media player in C# but when I want to make my test I have a problem.

I have to create a new object song with the following path:

@"C:\Users\Jesus Antonio\Desktop\JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3"

It works but when I change the computer I have to rewrite the entire path, My project is called JukeboxV2.0

In java I remember you can just write the path for example

@"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3"

This will save a lot of time because I can take my project to different computers and it works, but here I don't known how to do that, anyone know?

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3")

base directory + your filename

I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:

• added the file test.txt to my test project
• on the solution explorer hit alt-enter (file properties)
• there I set BuildAction to Content and Copy to Output Directory to Copy if newer, I guess Copy always would have done it as well

then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

Hopes this helps someone
