I have list of objects and I have another list of true false. 
 I wanna make list of all objects are true

 List1:(Curve 1,Curve 2 ,Curve 3 ) 
 Pattern list:(True,False,True) 
 Expected result: (Curve1,Curve3) 
 
 how can I make this function ?

You could write your own custom function and use it in a function node: 
 Something like this should work:

object [] MaskedList(object [] InList, bool [] Mask) { object OutList = {}; int c = 0; for (int i = 0; i < InList.Count; ++i) { if (Mask[i] == true) { OutList[c] = InList[i]; ++c; } } return OutList; }
