Making a file path dynamic

Question

I just want to Code an Launcher for the Game i currently making, but i ran into an Problem and i am an absolutely beginner as a Programmer.

Currently i have a Start Button with looks like this

private void startbtn_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process.Start("C:\\Users\\Windows\\Desktop\\Folder\\Underfolder\\Game.exe");
}

But i try to make it Dynamic, so the Launcher can work which ever the User install the Data (There is an Installer for everything) also the launcher is located in the same directory as the Game.exe

(The Code looks weird on the Post but it is correct)

Answer 1

The most reliable way I've found to do this is (assuming Game.exe is located in the same path as your Launcher.exe as you mentioned in your post):

var launcherExeDirectory = AppDomain.CurrentDomain.BaseDirectory;
var gameExeFullPath = Path.Combine(launcherExeDirectory, "Game.exe");

Then you can just do something like:

Process.Start(gameExeFullPath);

Answer 2

Just use GetCurrentDirectory

Process.Start(System.IO.Directory.GetCurrentDirectory + @"\game.exe");

///Or

Process.Start(AppDomain.CurrentDomain.BaseDirectory + @"\game.exe");

///or

Process.Start(Application.ResourceAssembly.Location + @"\game.exe");

///or

Process.Start( System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + @"\game.exe");
