使用LINQ填充具有特定数字范围的列表

Question

In order to populate a List<int> with a range of numbers from 1 to n I can use:

for (i=1; i<=n; i++)
{
   myList.Add(i);
}

Is there any way to achieve the same result by using LINQ inline expressions?

UPDATE

Assume I have a method getMonthName(i) that given the integer returns the name of the month. Can I populate the list directly with month names somehow by using Enumerable

Answer 1

Enumerable.Range(1,12).Select(getMonthName);

Answer 2

You want to use Enumerable.Range .

myList.AddRange(Enumerable.Range(1, n));

Or

myList = Enumerable.Range(1, n).ToList();

If you're asking this kind of question, you might want to look over the methods of System.Linq.Enumerable . That's where all this stuff is kept. Don't miss ToLookup , Concat (vs Union ), and Repeat .

Answer 3

对于月份名称，您可以使用Select() ：

var months = Enumerable.Range(1,n).Select(getMonthName);
