Collections query ??

Question

HI

Well is there any other way to add elements to generic collections[list<string>] or collection initializes  etc ..

Well issue here is if i want to add say 100 elements over and over i dont want to use collectionobject.add() over and over which is no a good option right .. 

So how to dynamically add elements to collection not using add method ...

Cheers 

TY
