enviroment variables in c#

My application "SC" is going to exectued standalone on a desktop (the user will enter a username / passwrd to connect to the database) Also it connects via another application that is already logged onto the database.

The question I have is how can i pick up the enviroment variables related to user / password / and database when the application "SC" if executed from another application that is already connected to the oracle database. The other application would be executed from a citrix server if that makes any difference ...

I have tried to use

test = Environment.GetEnvironmentVariable("USER");

MessageBox.Show("test = " + test + " \n"
, "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);

test is always blank wether its from the desktop or from the citrix application

the username /password is the oracle database, the application that executes "SC" is a windows gui app and the SC app is a WinFrom written in C#

thanks everyone for the help, it has helped me get to the information i need, in the end i used
what I found was that when the calling program called SC, it had looged onto the oracle database 1st, so the envirment variables where set for that instance, but when SC is called directly from windows you have not logged onto the database and those variableswhere not set

test = Environment.GetCommandLineArgs();
for (int i = 0; i < test.GetLength(0); i++)
{
if (test[i].StartsWith("USER="))
{ luser = test[i].Substring(5); }
else if (test[i].StartsWith("PASSWORD="))
{ lpswd = test[i].Substring(9); }
else if (test[i].StartsWith("DATABASE="))
{ ldb = test[i].Substring(9); }
}
