例如，我有以下数据：

YELLOW,SMALL,STRETCH,ADULT,T
YELLOW,SMALL,STRETCH,ADULT,T
YELLOW,SMALL,STRETCH,CHILD,F
YELLOW,SMALL,DIP,ADULT,F
YELLOW,SMALL,DIP,CHILD,F
YELLOW,LARGE,STRETCH,ADULT,T
YELLOW,LARGE,STRETCH,ADULT,T
YELLOW,LARGE,STRETCH,CHILD,F
YELLOW,LARGE,DIP,ADULT,F
YELLOW,LARGE,DIP,CHILD,F
PURPLE,SMALL,STRETCH,ADULT,T
PURPLE,SMALL,STRETCH,ADULT,T
PURPLE,SMALL,STRETCH,CHILD,F
PURPLE,SMALL,DIP,ADULT,F
PURPLE,SMALL,DIP,CHILD,F
PURPLE,LARGE,STRETCH,ADULT,T
PURPLE,LARGE,STRETCH,ADULT,T
PURPLE,LARGE,STRETCH,CHILD,F
PURPLE,LARGE,DIP,ADULT,F
PURPLE,LARGE,DIP,CHILD,F

我需要生成以下几组数据（注意上面数据的列会生成下面的数据个数）如果有5列，就会有4组数据，第一个单列，第二个2个，第三个3个，等等。最后一列被省略，是连接所有数据的 CLASS 列，数字是它在上述给定数据中的出现次数。

所以甚至可以有 50 列，也可以有 80 甚至更多。

复杂性还在于可以有 0 和 1 而不是单词，我们需要匹配相同的列。

希望你有这个问题。

我制作了以下代码来生成第一列。主要问题是其余列。

for (int i = 0; i < lsClasses.Count; i++)
            {
                for (int j = 0; j < lsUniqueOps.Count; j++)
                {
                    int count = FindInOrignalList(orignalList, lsClasses[i], lsUniqueOps[j]);
                    if (count != 0)
                    {
                        List<string> checkedItem = new List<string>();
                        checkedItem.Add(lsUniqueOps[j][0]);
                        checkedItem.Add(lsUniqueOps[j][1]);
                        checkedItem.Add(lsClasses[i]);
                        checkedItem.Add(count.ToString());
                        lsFirstItemSet.Add(checkedItem);
                    }
                }
            }

--------------------------------------------------

private static int FindInOrignalList(List<List<string>> orignalList, string lsClass, List<string> lsUniqueOp)
        {
            List<List<string>> tmpList = new List<List<string>>();
            int count = 0;
            for (int i = 0; i < orignalList.Count; i++)
            {
                for (int j = 0; j < orignalList[i].Count - 1; j++)
                {
                    if (orignalList[i][j] + "," + orignalList[i][orignalList[i].Count - 1] == lsUniqueOp[0] + "," + lsClass)
                        count++;
                }
            }
            return count;
        }

如果我没看错，你只列出最后没有“F”的市场事件。你只会得到“T”。那是对的吗？如果是这样，您可以从

  1. 删除 F'ed 的行，因为它们永远不会导致任何上升，
  2. 完全删除最后一列（因为只有 T 存在并且一行的存在已经暗示了它的真实性）
  3. 告诉我这是否是一项家庭作业（在这种情况下，您处于初级水平，需要与高级程序员不同的解释）。

我会假设你是精明的类型。然后，您可以应用 LINQ 和合适的数据结构来计算出现次数。就在我的脑海中 -DataSet和公司可能是一个不错的选择。Dictionary可能是另一个。
