Write file to project folder on any computer

Question

I'm working on a project for a class. What I have to do is export parsed instructions to a file. Microsoft has this example which explains how to write to a file:

// Compose a string that consists of three lines.
string lines = "First line.\r\nSecond line.\r\nThird line.";

// Write the string to a file.
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt");
file.WriteLine(lines);

file.Close();

I'm fine with that part, but is there a way to write the file to the current project's environment/location? I'd like to do that instead of hard coding a specific path (i.e. "C:\\test.txt").

Answer 1

Yes, just use a relative path. If you use @".\test.txt" ( btw the @ just says I'm doing a string literal, it removes the need for the escape character so you could also do ".\\test.txt" and it would write to the same place) it will write the file to the current working directory which in most cases is the folder containing your program.
