C# File directory issue

I have created a high score file for my game and I am having problems reading it.

When I change computers my USB drive changes letter .eg from drive E to drive G.

This is causing problems with reading the file. (as I use string path = @"g:\Scores.txt";)

So my question is.... can I set a default path to the program location??

My current code:-

string path = @"g:\Scores.txt";
            StringBuilder sb = new StringBuilder();
            using (StreamReader sr = new StreamReader(path))
            {
                while (sr.Peek() >= 0)
                {
                    sb.Append(sr.ReadLine());
                }
            }

any help is appreciated.

You should use your application path, not an absolute path. You may do something like this:

using System.IO;
using System.Windows.Forms;

string appPath = Path.GetDirectoryName(Application.ExecutablePath);

If your program is in the same folder as the file ( Eg. in G:\ ), then you can simply access the file with his name : `path = "Scores.txt". In that case there is no need to know where is the file

Is the game on your USB drive as well? Do you want to save the file in the same directory as the game, or in a directory somewhere around it? Do something like this:

using System;
using System.IO;
using System.Reflection;
...
string thisAsmFile = Assembly.GetExecutingAssembly().Location;
string thisAsmDir = Path.GetDirectoryName(thisAsmPath);
string highScoreFile = Path.Combine(thisAsmDir, "scores.txt");
