[Mono-dev] starting process in Linux environment
Hi
i'm trying to start a proces in linux but it fails.
the problem is the process argument, it doesnt recognize it.
Process procNetAdapters = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo(ifconfig);
startInfo.Arguments = | grep 'inet addr:';
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.CreateNoWindow = true;
procNetAdapters.StartInfo = startInfo;
procNetAdapters.Start();
using (StreamReader r = procNetAdapters.StandardOutput)
{
string line;
string removedLine;
while ((line = r.ReadLine()) != null)
{
if (!windowList.Contains(ADAPTER: + line))
{
windowList.Add(ADAPTER: + line);
}
}
}
procNetAdapters.Close();
}

Okay, in that case can you post the stack trace and error message?
Thanks,

hi
yes true, i forgot that, but i dont think thats the problem. because
without that processstartinfo, streamwriter writes it in the homefolder
and gives no error.

Are you on Linux or Windows? You're running a Linux program, but have a
Windows path in your StreamWriter!
There's your problem!
