Declaring an array of List Generic Class elements

[Guest]

Hello,

I am declaring an element like this:
public static List<myListElement> myList = new List<myListElement>();

I would like to declare an array of this myList.
How would I modify the declaration of myList so it will represents an array?

Thanks
Eitan

public static List<myListElement>[] myList = new List<myListElement>[4];

Hello Colin,
Thank you for your answer.

I tried the line below (before posting my question):
public static List<myListElement>[] myList = new
List<myListElement>[4]();
The difference is the brackets "()" after "[4]". The compiler generated an
error.

Can you explain to me why the error, and when would you need the brackets
"()"?

Thank you,
Eitan

Hi Eitan,

You can declare it like this:
public static List<myListElement>[] listArray = new List<myListElement>[10];

(To define an array of size 10)

But please note that each element in the array will still have to be
constructed. You could this in a for-loop:

///
for (int i = 0; i < listArray.Count; i++)
listArray = new List<myListElement>();
///

Hi Eitan,

If you take a look at my response it may be a bit clearer what is going on.
When you're defining the array, you aren't constructing the List<> objects,
just constructing an array of list objects. Parentheses are not required
for constructing an array, as the construction doesn't take parameters,
only a size of array to create given in the square brackets.

So, that being the case, you'll have to manually construct each List<>
object in your array.
