将列表拆分为多个列表
我有一个字符串列表，我发送到队列。我需要拆分列表，以便我最终得到列表的列表，其中每个列表包含最大（用户定义）的字符串数。因此，例如，如果我有一个列表与以下A，B，C，D，E，F，G，H，I和列表的最大大小为4，我想结束一个列表的列表，其中第一个列表项包含：A，B，C，D，第二个列表有：E，F，G，H，最后一个列表项只包含：我已经看了TakeWhile函数，这是最好的方法。
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. Anyone got a solution for this?
您可以设置列表< IEnumerable< string> ; 然后使用跳过和以分割列表：
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 包含，以及列表列表。
Now listOfLists will contain, well, a list of lists.
