[Python.NET] converting Pyobject to user defined type data structures

[Kaveripakam, Sathish]

Hi Brian,
 
Thanks for your reply.
 
In my case, "Spam" is a user defined "class" (It is not of standard
type: int,string, float etc.,) .My intention is to cast a PyObject to
the "Spam", which is a "Class" type..
 
When I try to execute the statement
 
Spam s = (Spam)ob.AsManagedObject(typeof(Spam));
 
the compilation went on smoothly, but during runtime, it has thrown an
error "cannot convert object to target type".
 
I was wondering, do I have any functions which provides the casting.
 
Regards

Sathish - If I understand correctly what you're asking, I think you
might need 
to use the AsManagedObject method to retrieve the CLR object that a
PyObject 
wraps:

PyObject ob = GetMyObject(...)

Spam s = (Spam)ob.AsManagedObject(typeof(Spam));

hope this helps,

-Brian

	Hi All,
	 
	I am reading a PyObject from Python in C#. In C# code, I  would
like to convert the PyObject to the user defined type. In this regard, I
used the call:
	

	<usrDefinedType> x  = (usrDefinedType)
Convert.ChangeType(pyObjectInstance,typeof(usrDefinedType)); 

	The compilation went on fine, but during runtime, I got an error
saying: "Object must implement IConvertible". 

	I was wondering, is there any other way to convert the PyObjects
to userdefined types ?

	Regards
