'The Paramter is incorrect', running a console program

[gilllyo]

I'm trying to run a program and pass it arguments. I know that the arguments provided are correct but I get a "The Parameter is incorrect" error. I has used the exact same arguments as provided in the 'arg' string to the program on the console and it worked as expecterd. (I copied the text directly from a watch I had set up)

I am using C#. Is there anything that I have missed?

Thank you.

            System.Diagnostics.ProcessStartInfo si = new System.Diagnostics.ProcessStartInfo();
            si.Arguments = arg;
            si.CreateNoWindow = true;
            si.FileName = ".\\planet.exe";
            si.RedirectStandardOutput = true;
            si.UseShellExecute = false;
            try
            {
                MessageBox.Show(si.FileName+ " "+si.Arguments);
                System.Diagnostics.Process prc=System.Diagnostics.Process.Start(si);
                prc.WaitForExit();
            }

hai gilllyo,

si.Arguments = arg;
// I think arg is an array
// We cant assign the array values to ProcessStartInf o.Arguments

"arg" isn't an array. Are you saying it should be or shouldn't be?

String arg = (String)e.Argument;
 

That's the line of code that takes the argument passed to a worker thread that's responsible for running the program (ie, same function) and using it for the argument to be passed to the program.
