在C#中将列表拆分为多个列表 [英] splitting a list into multiple lists in C#

问题描述

我有一个发送到队列的字符串列表.我需要拆分列表，以便最终得到一个列表列表，其中每个列表都包含最大(用户定义)的字符串数.因此，例如，如果我有一个包含以下A，B，C，D，E，F，G，H，I的列表，并且列表的最大大小为4，则我想以列表列表结尾，其中第一个列表项包含:A，B，C，D，第二个列表项包含:E，F，G，H，最后一个列表项仅包含:I.我看过"TakeWhile"功能，但不确定是否这是最好的方法.有什么解决办法吗?

I have a list of strings which I send to a queue. I need to split up the list so that I end up with a list of lists where each list contains a maximum (user defined) number of strings. So for example, if I have a list with the following A,B,C,D,E,F,G,H,I and the max size of a list is 4, I want to end up with a list of lists where the first list item contains: A,B,C,D, the second list has: E,F,G,H and the last list item just contains: I. I have looked at the "TakeWhile" function but am not sure if this is the best approach. Any solution for this?

推荐答案

您可以设置List<IEnumerable<string>>，然后使用Skip和Take拆分列表:

You can set up a List<IEnumerable<string>> and then use Skip and Take to split the list:

IEnumerable<string> allStrings = new[] { "A", "B", "C", "D", "E", "F", "G", "H", "I" };

List<IEnumerable<string>> listOfLists = new List<IEnumerable<string>>();
for (int i = 0; i < allStrings.Count(); i += 4)
{                
    listOfLists.Add(allStrings.Skip(i).Take(4)); 
}

现在listOfLists将包含一个列表列表.

Now listOfLists will contain, well, a list of lists.
