c# - 抓取列表的一部分按开始和结束索引

Question

这可能吗？

例如，如果我有

List<Item> myList = new List<Item>;

//added 100 of Items to myList

//then I want to grab items at indices 50 - 60

List<Item> myNewList = myList.?

如果不循环通过 myList，我该怎么做？谢谢你。

Answer 1

有一个方法可以检索这些项目，List.GetRange。 http://msdn.microsoft.com/en-us/library/21k0e39c.aspx

List<Item> myList = new List<Item>;
myList.GetRange(50, 10); // Retrieves 10 items starting with index #50

Answer 2

var myNewList  = myList.Skip(50).Take(10);

Answer 4

关于什么：

        List<string> myList = new List<string>();

        //added 100 of Items to myList
        for (int i=0; i<100; ++i)
        {
            myList.Add("blablabla");
        }

        //then I want to grab items at indices 50 - 60
        // Note: 50 - 60 inclusivly are actually 11 items
        List<string> myNewList = myList.GetRange(50, 11);
