Hi all,
I'm new to Python and IronPython, sorry if this is obvious. I haven't found
answer searching web or in IronPython In Action book...
I have embedded IronPython into silverlight app for scripting, which is
working (wow! Btw). I use scope.SetVariable for dictionaries which works as
expected.
However when passing in a list I am unable to access the objects within a
list.
For the example below when trying
x = books[0].Name
I get
TypeError: 'List[books]' object is unsubscriptable
If I do
x = books
I get back
System.Collections.Generic.List'1[testapp.PythonEngine+book]
If I do
Len(books)
I get back 4.
How do I access them individually (by name etc.)?
My code looks something like this:
Class book
{
int ID { get; set; }
String Name { get; set; }
String Author { get; set; }
String Description { get; set; }
}
...
List<book> _books = new List<book>();
_books.Add(new book { ID=1, Name="book1", Author="author1",
Description="Description1"});
_books.Add(new book { ID=2, Name="book2", Author="author2",
Description="Description2"});
_books.Add(new book { ID=3, Name="book3", Author="author3",
Description="Description3"});
_books.Add(new book { ID=4, Name="book4", Author="author4",
Description="Description4"});
...
_scope.SetVariable("books", _books);
Any help appreciated, thanks!
