Yes,It will work with this way but i need to create multiple instance of same class.If you see other function (@Execute() ) with static was working.

Please give me hint of doing without static.

Thanks

Hello,

 

you missed either @staticmethod decorator or the self argument for the Initialize method.

Subject: [Python.NET] Error in calling Python class method from C#

 

Hi,

 

I am facing issue while calling python class function in C# programme. Can anyone give me hint what is wrong in below programme.While running I am getting error in invoking Initialize() function of class.

 

Python module <Class.py> :

def test():

 print "Test called"

 return 1

 

class ClassTest:

  def __init__(self)

 

  def Initialize ():

   print " Initialize called"

   return 1

 

  @staticmethod

  def Execute():

   print "Execute called"

   return 1

 

C# Console Programme code snapshot :

PythonEngine.Initialize();

            using (Py.GIL())

            {

                PyObject testClassModule = PythonEngine.ImportModule("Class");

              

                //Calling module method

                PyObject result = testClassModule.InvokeMethod("test");

                Console.WriteLine("Test method result = {0}", result.ToString());

 

                PyObject classTest = testClassModule.GetAttr("ClassTest");

                classTest.InvokeMethod("Initialize "); -----------------------------> Error

                classTest.InvokeMethod("Execute");

           }

            PythonEngine.Shutdown();
