[IronPython] Update from IronPython v1.0 to IronPython v2.6

   Hi Curt,
I noticed the Microsoft.Scripting.Hosting.ObjectOperations.Call(object,
params object[])' is obsolete, you are correct, we should use Invoke
Is there any api to check whether specific function exists before call it in
the .py file? because if C# code call a nonexistent function in the .py
file, it will occurs runtime error.

Thank you.

Best Regards,
Evan Wang

 Hi Curt,
Thanks a lot for your instruction:)
Another option I tried yesterday like this:
            ScriptEngine engine = Python.CreateEngine();
            ScriptScope Scope = engine.CreateScope();
            ScriptSource source;
            source = engine.CreateScriptSourceFromFile("D:\\test.py");
            ObjectOperations operations = engine.Operations;
            object function = Scope.GetVariable("GetScriptInfo");
            int result = (int)operations.Call(function);

It works as well, but your option is better.

Best Regards,
Evan Wang

 One option is this:

            ScriptEngine engine = Python.CreateEngine();
            ScriptScope pyScope = engine.CreateScope();
            ScriptSource ss = engine.CreateScriptSourceFromFile("test.py");
            string address = engine.Operations.InvokeMember(pyScope,
