Question

I got this program written in C# WinForms.

im using system.diagnostic to create a CMD process.
with that cmd i want some arguments but they are not present or working :S
dont know why ?!

NOTE: im not sure how to use more than 1 argument, correct me if im wrong 😀
im trying to replicate the “copy /b %filename% lpt1” command….

here is my code:

    public void OutputBtn_Process_Click(object sender, EventArgs e)
    {
        foreach (FileInfo fi in listBox1.Items)
        {
            Process process1 = new Process();
            process1.StartInfo.UseShellExecute = false;
            process1.StartInfo.Arguments = "copy /b myfile.txt test.txt";
            //process1.StartInfo.LoadUserProfile = true;
            process1.StartInfo.FileName = "cmd.exe";
            process1.StartInfo.WorkingDirectory = Path.GetDirectoryName(fi.FullName);
            process1.Start();
        }
    }

Answer 1

Try this

 process1.StartInfo.Arguments = "/C \"copy /b myfile.txt LPT1:\"";
