What is list, exactly? If it UI? Or just a collection? If it is, tag the UI library.

list<int>=new list<int>; collection.

We don't know how you want to use such collection: for access by key (then see Solution 1), or as list. If as list, create a structure or a class, for example:

C#

struct ListElement {
   public int Id,
   public string Name,
}

// ...

List<ListElement> list = new List<ListElement>();

[EDIT]

Another option is using the tuple: http://msdn.microsoft.com/en-us/library/system.tuple.aspx[^].

Solution 1

If you want a List consisting of an integer key with a string value, then you would use Dictionary<int,string>.

I voted 4, because we really don't know if OP wants to use access by key. Maybe it still have to be a list, then the solution is the list of struct/class instance.
Please see my answer (which of course credits yours).
