Declaring an array of linked list in C#

How do I declare an array of some class in C#? I wonder if it is even allowed or possible.

I got the compile error message "Array size cannot be specified in a variable declaration (try initializing with a 'new' expression)" when I tried to declare an array of linked lists.

public LinkedList<LevelNode>[2] ExistingXMLList;

Also, if I wanted to create a small array of strings, isn't this the way:

string [2] inputdata;
