processstartinfo arguments problem

Hi all,
I want to call cce.exe with 7 arguments (cce 5 50 0 filename 0 file name)
when I run this code it gives an error "process find a valid specification file "
I may be the arguments are incorrect.

if (g.Count() > 1)
                    {
                        // sw.Write(String.Format("{0,-15} {1,-15} ", g.Key.source, g.Key.dest));
                        double packet = Convert.ToDouble(g.ElementAt(0)["pkts"]);

                        TextWriter swtest = new StreamWriter(@"C:\Hellotest.txt", true);
                        TextWriter sw = new StreamWriter(@"C:\Hello.txt", true);
                        for (int i = 1; i < g.Count(); i++)
                        {
                            packet = Convert.ToDouble(g.ElementAt(i)["pkts"]);
                            // if (i > 1) sw.Write(new string(' ', 34));
                            //richTextBox1.Text += "ip.src: " + g.Key.source + "ip.dst: " + g.Key.dest + "difference: " + (time2 - time1).ToString() + "\r\n"; //"winc:" + winc + "   FP:" + FP1.Count() + "   TP:" + TP1.Count() + "   FPRate:" + FPRate + " Detection rate:" + DetectionRate + " bot:" + g.Count + "\r\n";

                            sw.WriteLine(packet);
                            swtest.WriteLine(packet);
                        }
                        sw.Close();
                        swtest.Close();
                        var psi = new ProcessStartInfo
                        {
                            FileName = @"c:\Users\botnet\Desktop\entropy\entropy\cce.exe",
                            Arguments = "cce"+5+ 50+ 0+ @"C:\Hellotest.txt" + 0 + @"C:\Hello.txt",
                            UseShellExecute = false,
                            RedirectStandardOutput = true,
                        };
                        var process = Process.Start(psi);
                        if (process.WaitForExit((int)TimeSpan.FromSeconds(10).TotalMilliseconds))
                        {
                            var result = process.StandardOutput.ReadToEnd();
                            if (Convert.ToDouble(result) < 2)
                                srcaddress.Add(g.Key.source.ToString());
                            MessageBox.Show(result.ToString());
                        }

                    }
Please help me

Sorry, that's because of a typo in my first response - ']' instead of '}' - in two places :(

Try this corrected version:

Arguments = String.Format("{0} {1} {2} {3} {4} {5} {6}", "cce", 5, 50, 0, @"C:\Hellotest.txt", 0, @"C:\Hello.txt"),

Hi Vulpes,

Thanks for your response, but it does not work, it gives an error like: Input string was not in a correct format.

Well, I haven't looked at the rest of the code but there's definitely something wrong with the Arguments property as you haven't separated the individual arguments with spaces.

So I'd replace:

Arguments = "cce"+5+ 50+ 0+ @"C:\Hellotest.txt" + 0 + @"C:\Hello.txt",

with:

Arguments = String.Format("{0} {1} {2} {3] {4} {5} {6]", "cce", 5, 50, 0, @"C:\Hellotest.txt", 0, @"C:\Hello.txt"),
