2You should set the current working directory to what the invoked program expects before invoking it. – Thorbjørn Ravn Andersen Jan 25 '17 at 00:35

yes I just think about it, but how I set the working directory for the jar? I tried with -cp argument but no result – DJ Vickz Jan 25 '17 at 01:04

You must do this in the surrounding environment where you invoke the java command. – Thorbjørn Ravn Andersen Jan 25 '17 at 16:22

please help I am getting crazy with this, I can't modify the jar file, it's pre-compiled and is not my project, I only invoke it from my C# application, what to do? :( – DJ Vickz Jan 27 '17 at 03:22

I can only guess, because the lines of code are missing that you use to invoke the java program from within your C# program. It is also unclear what exactly you are trying to achieve. Decide between changing the "current work directory" in the child or in the main process.
child process
I assume you want to execute something like this java -jar path\to\some.jar using code similar to this:
using System.Diagnostics;
//...
ProcessStartInfo p = new ProcessStartInfo();
p.Arguments = new string[]{"-jar", "path\to\some.jar";
p.FileName = "java.exe";
p.WindowStyle = ProcessWindowStyle.Hidden;
p.CreateNoWindow = true;
using (Process proc = Process.Start(start))
{
proc.WaitForExit();
}
Adapted from here
Then you can just add this line
p.WorkingDirectory = "path\to";
Adapted from here
to setup your child process covered by the p instance with a specific current work directory. This will set the current work directory for the invocation of your java child process.
main process
To setup the current work directory for the surrounding main process add this line to your program:
System.IO.Directory.SetCurrentDirectory("some\other\path");
