Re: [Python.NET] managed exception stack trace.

I am using pythonNet with a great pleasure, thanks a lot for that piece

IMHO, a wiki would be very very useful for this project, as I would be 
ready to contribute...

One question:
How do I print out managed exceptions full stack trace?
   

Hi Stan - 

A trick you might be able to use is:
print CLR.System.Environment.StackTrace
 

unfortunately not:
try:
     #do stuff that throws exception in the CLR
   except:
     print Environment.StackTrace
gives what printed below, wich is fairly unusable.
  at System.Environment.GetStackTrace(Exception e)^M
  at System.Environment.GetStackTrace(Exception e)^M
  at System.Environment.get_StackTrace()^M
  at System.Reflection.RuntimeMethodInfo.InternalInvoke(Object obj, 
BindingFlag
s invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, 
Boolean i
sBinderDefault, Assembly caller, Boolean verifyAccess)^M
  at System.Reflection.RuntimeMethodInfo.InternalInvoke(Object obj, 
BindingFlag
s invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, 
Boolean v
erifyAccess)^M
  at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, 
BindingFlags invoke
Attr, Binder binder, Object[] parameters, CultureInfo culture)^M
  at System.Reflection.RuntimePropertyInfo.GetValue(Object obj, 
Object[] index)

  at Python.Runtime.PropertyObject.tp_descr_get(IntPtr ds, IntPtr ob, 
IntPtr tp
)^M
  at Python.Runtime.Runtime.Py_Main(Int32 argc, String[] argv)^M
  at Python.Runtime.PythonConsole.Main(String[] args)

Exceptions are in kind of an odd state right now - the C Python runtime 
really wants exceptions to be old-style Python classes, and the fact 
that managed exceptions aren't causes some problems in the current 
version of Python for .NET. I'm still hoping to find a sneaky way 
around it or successfully lobby the Python devs to remove this 
restriction for a future Python version.
