Question

I have successfully opened command prompt window using C# through the following code.

    Process p = new Process();
    p.StartInfo.FileName = "cmd.exe";
    p.StartInfo.WorkingDirectory = @"d:\pdf2xml";
    p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardOutput = true;
    p.StartInfo.RedirectStandardInput = true;


    p.Start();

    p.StandardInput.WriteLine(@"pdftoxml.win32.1.2.7 -annotation "+filename);

    p.StandardInput.WriteLine(@"cd D:\python-source\ds-xmlStudio-1.0-py27");

    p.StandardInput.WriteLine(@"main.py -i example-8.xml -o outp.xml");

    p.WaitForExit();

But, i have also passed command to change the directory.

problems:

1. how to change the directory location?
2. Cmd prompt will be shown always after opened…

Please guide me to get out of those issue…

You can use p.StandardInput.WriteLine to send commands to cmd window. For this just set the p.StartInfo.RedirectStandardOutput to ture. like below

        Process p = new Process();
        p.StartInfo.FileName = "cmd.exe";
        //p.StartInfo.Arguments = @"/c D:\\pdf2xml";
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardOutput = true;
        p.StartInfo.RedirectStandardInput = true;
        p.Start();

        p.StandardInput.WriteLine(@"cd D:\pdf2xml");
        p.StandardInput.WriteLine("d:");
