合并文件夹一

背景

需要按照一定规则合并大量文件夹
这些文件夹是按照命名分类的
这些文件夹的命名存在一定规律，比如A_001_005,A_004-010，需要把连续的文件夹合并

需求说明

1、根据指定目录下，找到文件夹所在根目录；该目录下包含需要合并的文件夹如：

2、将待合并的文件夹，合并到一个主文件夹中；
例如上图两个文件夹中，任务号相同，将其中的子文件夹都合并到一个主文件夹（TRIPLESAT_1_PMS_20170112_000BAEVI）中
3、其中重复的不合并，即第二个文件夹中的004和005不需要剪切到主文件夹中。
4、全部合并完成后，删除原文件夹

代码

主逻辑代码：

string[] strFiles1 = Directory.GetDirectories(_strOldmerge, "TRIPLESAT_*_001_*", SearchOption.AllDirectories);            string[] strFiles2 = Directory.GetDirectories(_strOldmerge, "TRIPLESAT_*_002_*", SearchOption.AllDirectories);            List<string> list = new List<string>();            list = strFiles1.ToList();            list.AddRange(strFiles2.ToList());            m_Log.Info("所有001和002开头文件获取完毕");            int index = 1;
