.Net开发复习与总结
1.文件操作
1.1递归目录，查找所有文件
1 #region 递归目录路径 2 private List<string> GetDirs(string path) 3 { 4 string[] dirs = Directory.GetDirectories(path); 5 List<string> result = new List<string>(); 6 foreach(string dir in dirs) 7 { 8 result.Add(dir); 9 } 10 if (dirs.Length > 0) 11 { 12 foreach (string dir in dirs) 13 { 14 result.AddRange(GetDirs(dir)); 15 } 16 } 17 return result; 18 } 19 #endregion 20 21 //调用 22 List<string> strdirs = GetDirs(path); 23 List<string> strfiles = new List<string>(); 24 foreach (string dir in strdirs) 25 { 26 foreach (string file in Directory.GetFiles(dir,"*汇总*.xls")) 27 { 28 strfiles.Add(file); 29 } 30 }
1.2 获取文件目录与文件名：
1 #region 获取文件路径设置 2 private List<string> GetFileSet(string par_path) 3 { 4 List<string> result = new List<string>(); 5 result.Add(Path.GetDirectoryName(par_path)); 6 result.Add(Path.GetFileNameWithoutExtension(par_path)); 7 return result; 8 } 9 #endregion
2.导入导出Excel与数据统计：
