How to run copy command using command line in c# ?

Hi,

Please try some codes below:

 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 /a D:\\doc1.txt + D:\\doc2.txt D:\\doc3.txt";
            process.StartInfo = startInfo;
            process.Start();

Best Wishes!
