If you want to use Linq then you can use the following snippet:

var listNumber = dicNumber.Keys.ToList();

Answer 3

If you want convert Keys:

List<string> listNumber = dicNumber.Keys.ToList();

else if you want convert Values:

List<string> listNumber = dicNumber.Values.ToList();

Answer 4

foreach (var item in dicNumber)
{
    listnumber.Add(item.Key);

listNumber = dicNumber.Select(kvp => kvp.Key).ToList();

listNumber = dicNumber.Keys.ToList();

var keys = new List<string>(dicNumber.Keys);
