Streamreader to a relative filepath

Question

I was wondering, if anyone could tell me how to point a StreamReader to a file inside the current working directory of the program.

E.g.: say I have program Prog saved in the directory "C:\ProgDir\". I commit "\ProgDir" to a shared folder. Inside ProgDir is another directory containing files I'd like to import into Prog (e.g. "\ProgDir\TestDir\TestFile.txt") I'd like to make it so that the StreamReader could read those TestFiles, even when the path to the directory has changed;

(E.G., on my computer, the path to the Testfiles is

C:\ProgDir\TestDir\TestFile.txt

but on the other person's computer, the directory is

C:\dev_code\ProgDir\TestDir\TestFile.txt

).

How would I get a StreamReader to be ale to read from TestFile.txt on the other person's computer? (to clarify, the filenames do not change, the only change is the path ProgDir)

I tried the following:

string currentDir = Environment.CurrentDirectory;
DirectoryInfo directory = new DirectoryInfo(currentDir);
FileInfo file = new FileInfo("TestFile.txt");

string fullDirectory = directory.FullName;
string fullFile = file.FullName;

StreamReader sr = new StreamReader(@fullDirectory + fullFile);

( pulled this from : Getting path relative to the current working directory?)

But I'm getting "TestFile does not exist in the current context". Anyone have any idea as to how I should approach this?

Thank you.

Answer 1

Is the Folder "TestDir" always in the executable directory? if so, try this

    string dir =System.IO.Path.GetDirectoryName(
      System.Reflection.Assembly.GetExecutingAssembly().Location);

    string file = dir + @"\TestDir\TestFile.txt";

This will give you the path of the exe plus the folder inside it and the textfile
