How to send data from C# to Python

How can i send this list to list in Python script? This is so big for sending as arguments. Thank you. 

 List<String> cefList= new List<String>();
               for(int i=0; i<1000; i++){
                cefList.Add("CEF:0|ArcSight|ArcSight|6.0.3.6664.0|agent:030|Agent [test] type [testalertng] started|Low|

You need to serialize the data to a common format that is accessible from both C# and Python. For example - XML or JSON. I would recommend using JSON.

Then you have several options:

  • Use sockets to transfer the data.
  • Use http to transfer the data.
  • Write to a file from C# and read that file from Python

Sockets would probably be faster. Using http might be easier. With files, you will need to have some sort of scheduling or notification system to let your Python program know when you have written to the file.

Since your C# program runs the python script, I guess the easiest solution would be to redirect the standard input of the python process:

     Process pyProc = Process.Start(
        new ProcessStartInfo("python.exe", @"/path/to/the/script.py")
        {
           RedirectStandardInput = true,
           UseShellExecute = false
        }
     );
     for (int ii = 0; ii < 100; ++ii)
     {
        pyProc.StandardInput.WriteLine(string.Format("this is message # {0}", ii));
     }

At the python script side, you just need to use built-in function raw_input like below (please note the function has been renamed to raw_input in 3.x):

while True:
    data = raw_input()
    print(data)
