The first question is why are you going through all the trouble of using the command prompt to create a directory? Why are you not using the built in features of .NET?

Solution 1

Because "md" and "pp" are not recognised parameters to cmd.exe

If you look here: http://ss64.com/nt/cmd.html[^] you will find all the things that the cmd application will know.

And before you ask, I suspect that "md" will not work as a Process either, as it is a built in DOS command.

As Wes and Sandeep have said: use the framework command instead: Directory.CreateDirectory[^]

Set the command to "java.exe" instead of "cmd.exe" and set the rest as the parameters.
You may need to locate the "java.exe" file and include it's path.

Did you look at the link provided above for cmd.exe parameters?
If you want to see the command window to watch the output of your java.exe look at using these parameters
Options
/C Run Command and then terminate

/K Run Command and then return to the CMD prompt.
This is useful for testing, to examine variables

Command : The command, program or batch script to be run.
This can even be several commands separated with '&'
(the whole should also be surrounded by "quotes")

Hi All,

I could solve with the following code

ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe");
processStartInfo.RedirectStandardInput = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.UseShellExecute = false;
processStartInfo.WorkingDirectory = "path";
processStartInfo.WindowStyle = ProcessWindowStyle.Maximized;
Process process = Process.Start(processStartInfo);

if (process != null)
{

string a= @"path -d";
string b = @"path -f";
process.StandardInput.WriteLine("java -jar CocoImport.jar -s " + a + " " + b +@"\");

//process.StandardInput.WriteLine("yourCommand.exe arg1 arg2");

process.StandardInput.Close(); // line added to stop process from hanging on ReadToEnd()

string outputString = process.StandardOutput.ReadToEnd();

}
