Hi Guys

I am trying to open the python compiler from my c# app and compile a script. After the the code below executes it just shows the python compiler opening up , but its blank. What could be wrong??

string str = "python.exe";
Process process = new Process();
process.StartInfo.FileName = str;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput = false;
process.Start();
System.IO.StreamWriter SW = process.StandardInput;
SW.WriteLine("import py_compile\r\n");
SW.WriteLine("py_compile.compile( \"IMAP2.PY\" )\r\n");

Solution 1

It is possible that your python compiler does not read from standard input. Test it: create a script file containing your two commands, run a command shell, and pipe your script into it by typing "python <MyScriptFile". If it works, at least you know it does read from stdin!
If it doesn't, then you may be on your own... Can you not provide this info via command line arguments?

do you mean open the python.exe compiler myself, and type my commands in? If so , I have done this.

Solution 2

Try setting process.StartInfo.RedirectStandardOutput = false; to true and try again.
