My code :

Ok, i found some TextNode, TextElement and ImageInstance. But my filters are not working.

Is there any documentation of filter ?

My code :

FilteredElementCollector collector = new FilteredElementCollector(DocFamily);
ICollection<Element> lines = collector.OfCategory(BuiltInCategory.OST_Lines).ToElements();
ICollection<Element> texts = collector.OfClass(typeof(TextNote)).ToElements();

Where is not error ?

Dear Pierre, 

You really do need to learn to search the Internet.

In this case, for instance, you can just search for 'Revit API filtered element collector':

https://duckduckgo.com/?q=revit+api+filtered+element+collector

Please practice this for a bit before asking the next question.

Best regards,

Jeremy

The specific problem that you ran into was discussed in the note on reinitialising the filtered element collector:
