Question

🙂

I have a software which can be executed via command line, and now I want it to be executed directly from my C# app. Sadly, there is no error but I still can’t do it. 🙁

The path of .exe file of the software is C:\program files\mysoftware.exe

The command I would like to input is
cd c:\program files\mysoftwareFolder
enter
mysoftware.exe d:\myfolder\file1.xxx d:\myfolder\file2.xxx -mycommand
enter
exit

The commands above work so well in the actual command prompt, but they just don’t work from my C# code.

Here is the code:

        Process cmdprocess = new Process();
        System.Diagnostics.ProcessStartInfo startinfo = new System.Diagnostics.ProcessStartInfo();
        startinfo.FileName = "cmd";
        startinfo.WindowStyle = ProcessWindowStyle.Hidden;
        startinfo.CreateNoWindow = true;
        startinfo.RedirectStandardInput = true;
        startinfo.RedirectStandardOutput = true;
        startinfo.UseShellExecute = false;
        cmdprocess.StartInfo = startinfo;
        cmdprocess.Start();
        System.IO.StreamReader sr = cmdprocess.StandardOutput;
        System.IO.StreamWriter sw = cmdprocess.StandardInput;
        sw.WriteLine(@"echo on");
        sw.WriteLine(@"c:");
        sw.WriteLine(@"cd" +@"program files\mysoftwarefolder");
        sw.WriteLine(@"mysoftware.exe" +@"d:\myfolder\file1.xxx" +@"d:\myfolder\file2.xxx" +@"-mycommand");
        sw.WriteLine(@"exit");
        sw.Close();
        sr.Close();

I guess the incorrect parts might be “startinfo.FileName = “cmd”;” or the way I typed the command in the code, but I have no idea how to correct them. 🙁

Please tell me what I did wrong. I appreciate every answer from you! :)))

UPDATE Thank you for your helps! I tried writing the command in batch file, but it only works in debugging mode. (I forgot to tell you guys that I am developing a web service.) When I run my external project which will use this C# service, it won’t work. I don’t know whether I should add something to my code or not.

help meeeeee pleaseeeee (T___T)

Write these commands in a batch file and execute the batch file.

In batch file:

cd c:\program files\mysoftwareFolder 
mysoftware.exe
d:\myfolder\file1.xxx
d:\myfolder\file2.xxx -mycommand 
exit

Code:

Process cmdprocess = new Process();
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = "path to batchfile.bat";
startinfo.WindowStyle = ProcessWindowStyle.Hidden;
startinfo.CreateNoWindow = true;
startinfo.RedirectStandardInput = true;
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
cmdprocess.StartInfo = startinfo;
cmdprocess.Start();
