Visual Studio 2015 Command Prompt issues

Question

I have a Visual Studio 2015 program that calls a command prompt. How do I write 2 lines to the command prompt? This is my current code:

System.Diagnostics.Process process = new System.Diagnostics.Process();
                    System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
                    startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
                    startInfo.FileName = "cmd.exe";
                    startInfo.Arguments = "/C copy " + calibrT1 + "_CDF.hex\"" + calibrT1 + "_ECC_CDF.hex\"";
                    process.StartInfo = startInfo;
                    process.Start();
 startInfo.Arguments = "/C c:\\ti\\hercules\\nowECC\\2.21.00\\nowECC -f035 -r4 -i "+ calibrT1 + "_ECC_CDF.hex\" -a ";
                    //MessageBox.Show("Tester");
                    process.StartInfo = startInfo;
                    process.Start();

As an interesting note. This current code does not work. However if the MessageBox.Show("Tester") is not commented out it does work. As such I can determine my lines of code are correct and work as I wish, however do not work sequentially without the MessageBox. I can't work out why as I can see no logical reason why a message box should effect my command prompt.

Thanks for any help.

You need to wait before starting the new one. So need to put WaitForExit before (this does the job that the MessageBox was doing).

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C copy " + calibrT1 + "_CDF.hex\"" + calibrT1 + "_ECC_CDF.hex\"";
process.StartInfo = startInfo;
process.Start(); 
process.WaitForExit(); // Wait First                       
startInfo.Arguments = "/C c:\\ti\\hercules\\nowECC\\2.21.00\\nowECC -f035 -r4 -i "+ calibrT1 + "_ECC_CDF.hex\" -a ";

process.StartInfo = startInfo;
process.Start();
