我需要生成以下几组数据（注意上面数据的列将生成下面的数据）如果有5列，将有4组数据，第一组有单列，第二组有2，第三组用3，依此类推。最后一列被省略，并且是CLASS列，所有数据都与该列连接，数字是上面给定数据中出现的数字。

所以甚至可以有50列，可以有80列甚至更多。

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。

希望你有问题。

我已经制作了以下代码来生成第1列。主要问题是其余的栏目。

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;
        }

Answer 1

如果我看得正确，你只能列出最后没有“F”市场的出现。你只得到“T”。那是对的吗？如果是这样，你可以从

开始

删除F'ed的行，因为它们永远不会导致任何upcount，
完全删除最后一列（因为只有T在那里而且一条线的存在已经暗示其真实性）
告诉我这是否是一个作业（在这种情况下，你处于初级水平，需要与高级程序员不同的解释）。

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

以特定格式组合和加入给定数据
