If I wanted to write a stub in C#, how do I get access to a PythonEngine that represents the python environment that called the C# code? Just calling IronPython.Hosting.PythonEngine() seems to get me a new environment. ___ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
Re: [IronPython] custom ConfigurationSection in IronPython
I have another related question. The Item property of System.Configuration.ConfigurationElement (base class for ConfigurationSection) doesn't seem to be accessible from IronPython. Is this because its overloaded by parameter type? Is there a way to access it from IronPython?

Re: [IronPython] custom ConfigurationSection in IronPython
Ahh, you're right - currently it looks like we won't ever get non-public indexers (this one is family or assembly, which is protected internal in C# speak). This is a bug, I've opened CodePlex bug #2766 for this (http://www.codeplex.com/WorkItem/List.aspx?ProjectName=IronPython). A simple workaround would be to write a class in C# that derives from this and exposes these publicly, and then use that class from IronPython. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Ferrara Sent: Thursday, August 31, 2006 1:14 PM To: Discussion of IronPython Subject: Re: [IronPython] custom ConfigurationSection in IronPython On Aug 31, 2006, at 4:00 PM, Dino Viehland wrote: The Item property is the default indexer, so you should be able to access it using foo[index].
