I am doing a launcher, however I would like to leave the files with a "fixed" path, the launcher is in the same folder as the file to be started, but I do not know how I could create a "midway", something like in html, that just put a piece of the path, if it is in the same folder, as is the case.
I'm using forms, .NET 3.5.
The folders look like this:
folder x / folder launcher / ...
folder x / folder prog /...
In C #, you can get the path to the program executable to be executed.
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string path = Uri.UnescapeDataString(uri.Path);
Where Assembly is in the namespace System.Reflection .
This gives us the path to the launcher executable . But this is not what is intended. If the launcher is "C: / x folder / launcher folder / launcher.exe", we want to have the path to "C: / folder x / folder prog /".
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string launcherPath = Uri.UnescapeDataString(uri.Path); //launcher.exe
string launcherDir = Path.GetDirectoryName(launcherPath); //pasta launcher
string appDir = Path.GetDirectoryName(launcherDir); //pasta x
string programPath = Path.Combine(appDir, "pasta prog", "program.exe");
Path belongs to the namespace System.IO .
With this code, we get the path to the program to run in the programPath variable.
But there is a simpler way to get relative paths. For this, we will combine the methods Path.Combine and Path.GetFullPath .
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(codeBase);
string launcherPath = Uri.UnescapeDataString(uri.Path);
string programPath = Path.GetFullPath(Path.Combine(launcherPath, "../../pasta prog/program.exe"));
The name of this is not "fixed path" but rather "relative path" ... but I think I understand what you mean, actually the string is fixed, representing a path relative. =)
I do not see problems using a relative path ... I just tested and it works perfectly:
var proc = Process.Start(@"..\pasta prog\nomeDoPrograma.exe");
Attention to creating a launcher shortcut
Note that the relative path is resolved relative to the path indicated in Environment.CurrentDirectory . If you create a shortcut to the launcher, the property that indicates the start path will be passed to this .Net environment variable.
