跨多个项目引用解决方案文件夹中的 txt 文件以进行作业分配

Question

Basics of assignment

1. Use Visual Studio (I'm in 2019, thank you school!)
2. Create console app that displays Magic 8 Ball style responses randomly to any text entered in line.
   • This list is stored as a .txt file somewhere within the solution
3. Create windows form app that allows a user to enter new responses that are saved to the list pulled in the console app above
   • This only accepts one line at a time with a listbox displaying the results and a save button for saving. Form has label ("Enter a magic response!"), text box for input, list box for displaying list from .txt file, and save button to add text box entry to .txt file.

I don't know how to reference across projects, and my developer lingo is still too underdeveloped for me to conduct a worthwhile Google search. I simply don't know how to reference a relative path that keeps things contained. I only know how to reference an absolute path:

StreamWriter outputfile;
outputfile = File.AppendText(@"C:\Users\...some-file-path...\Homework2\responses.txt)

Or deeper if it's in the bin\\debug folder. Speaking of, I don't care if it's in the debug folder of one project or another, or in the main solution folder.

I just want it to work since it's homework (although an explanation of common industry best practices would not be unappreciated, even though I'm going into IT). How do I reference the solution folder as the start of the path to which I need to find a file? I would ask if that's possible, but I know the reality of programming is that anything is possible if you're just willing to put enough knuckle grease into the project.

Answer 1

You can use .. to go up a directory relative to the current one. So going from C:\\Windows\\Temp using ..\\..\\ProgramData would get you to C:\\ProgramData .

The current dir is referenced with .\\ for going downwards in the tree. So using the previous example .\\Temp1 would get you to C:\\Windows\\Temp\\Temp1
