simple approach           List lt int gt    a   new List lt int gt  100           for  int i   0  i  lt  a Length  i                          a i    new List lt int gt                 or LINQ approach          var b   Enumerable Range 0 100  Select  i   gt new List lt int gt     ToArray

You do like this   List lt int gt    a   new List lt int gt  100     Now you have an array of type List lt int gt  containing 100 null references  You have to create lists and put in the array  for example   a 0    new List lt int gt

I can suggest that you both create and initialize your array at the same line using linq   List lt int gt    a   new List lt int gt  100  Select item  gt new List lt int gt     ToArray

List lt int gt     a   new List lt int gt  100     You still would have to allocate each individual list in the array before you can use it though   for  int i   0  i  lt  a Length  i        a i    new List lt int gt

Since no context was given to this question and you are a relatively new user  I want to make sure that you are aware that you can have a list of lists  It s not the same as array of list and you asked specifically for that  but nevertheless   List lt List lt int gt  gt  myList   new List lt List lt int gt  gt       you can initialize them through collection initializers like so   List lt List lt int gt  gt  myList   new List lt List lt int gt  gt     1 2 3   4 5 6   7 8 9
