从List中获取5个字符串组

Question

我有一个List<string>,我想从中获取5个项目组.没有键或任何简单的分组......但它总是5的倍数.

例如

{"A","16","49","FRED","AD","17","17","17","FRED","8","B","22","22","107","64"}

参加团队:

"A","16","49","FRED","AD"
"17","17","17","FRED","8"
"B","22","22","107","64"

但我无法找到一个简单的方法来做到这一点!

很确定它可以用枚举和Take(5)来完成......

Answer 1

 List<List<string>> result = new List<List<string>>();
 for(int i = 0; i < source.Count; i += 5 )
      result.Add(source.Skip(i).Take(5).ToList());

像这样？

Answer 2

你可以使用整数除法技巧:

List<List<string>> groupsOf5 = list
    .Select((str, index) => new { str, index })
    .GroupBy(x => x.index / 5)
    .Select(g => g.Select(x => x.str).ToList())
    .ToList();
