Convert list <int> to list <List <int>>

Is it possible to convert List<int>to List<List<int>>in C #? When I use this design

List<int>element=new List<int>();
List<List<int>>superElement= new List<List<int>>(element);

I get an error, but can I do it differently?

You can do it as follows:

List<List<int>> superElement = new List<List<int>>();
superElement.Add(element);

source 
List<int>element=new List<int>();
List<List<int>>superElement= new List<List<int>> { element };

That will work. You cannot pass a list in the constructor.

:

var element = new List<int>();
var superElement = new List< List<int> >(){ element };

.

List<int> element = new List<int>();
List<List<int>> superElement = new List<List<int>> { element };
