Read list of lists object

How To read many lists in component’s output when i used this code

The simplest answer is: you can’t

The longer answer is: you need to covert your nested array into grasshopper datatree. But I can’t help you with c#

thanx for you IVELIN
but can you give me the main idea of how handle with datatree even if with Python to achieve the same result

You should search the forum. I am sure there are examples using csharp
