As a school project my class made a simple programing language in python 3. Now we made a simple ide in c# that should execute python script in a new console window. I was wondering what is most efficient way to do it. (I should execute it with parameters)

I tried to use IronPython and with ProcessStartInfo but IronPython was not working every time i tried and ProcessStartInfo would close automatically. Here's my project mediafire.com/?81ppkgl5fpel595Sava Filipovic– Sava Filipovic2015-05-14 11:35:41 +00:00Commented May 14, 2015 at 11:35

You can use ProcessStartInfo
int parameter1 = 10;
int parameter2 = 5
Process p = new Process(); // create process to run the python program
p.StartInfo.FileName = "python.exe"; //Python.exe location
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false; // ensures you can read stdout
p.StartInfo.Arguments = "c:\\src\\yourpythonscript.py "+parameter1 +" "+parameter2; // start the python program with two parameters
p.Start(); // start the process (the python program)
StreamReader s = p.StandardOutput;
String output = s.ReadToEnd();
Console.WriteLine(output);
p.WaitForExit();

I tried this and consloe opens and closes without any output

I won't be able to access that until later today, but I have corrected the script so it doesn't parse the output. It works correctly for a
print "Hello World" app.There is two way to run the python script:
- One way is to run the python script is by running the python.exe file:
Run the python.exe file using ProcessStartInfo and pass the python script on it.
private void run_cmd(string cmd, string args) {
ProcessStartInfo start = new ProcessStartInfo();start.FileName = "my/full/path/to/python.exe"; start.Arguments = string.Format("{0} {1}", cmd, args); start.UseShellExecute = false; start.RedirectStandardOutput = true; using(Process process = Process.Start(start)) { using(StreamReader reader = process.StandardOutput) { string result = reader.ReadToEnd(); Console.Write(result); } } }
- Another way is using IronPython and execute the python script file directly.
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;private static void doPython() { ScriptEngine engine = Python.CreateEngine(); engine.ExecuteFile(@"test.py"); }
