推荐答案

您可以使用LINQ轻松完成此操作，如下所示：

You can easily do that with LINQ, like so:

static IList<int> GetPage(IList<int> list, int pageNumber, int pageSize = 10)
{
    return list.Skip((pageNumber - 1) * pageSize).Take(pageSize).ToList();
}

static void Main()
{
	IList<int> list = Enumerable.Range(1, 100).ToList();
	
	Console.WriteLine(String.Join(", ", GetPage(list, 1, 10)));
	Console.WriteLine(String.Join(", ", GetPage(list, 2, 10)));
}

但是，这确实要求你将整个集合放在内存中。如果这没问题，这就是要走的路。

*抱怨粘贴的东西在CP *

However, this does require you to have the whole collection in memory. If that's no problem, this is the way to go.
