以刪除檔案lastname + “.rar”為例

  public static void DeleteFile(string dirRoot)
        {
            string filepath1 = System.IO.Directory.GetCurrentDirectory();
            string[] filename = filepath1.Split('\\');
            string lastname = filename[filename.Length - 1];
            string deleteFileName = lastname + ".rar"
 
;//要刪除的檔名稱
            try
            {
                string[] rootDirs = Directory.GetDirectories(dirRoot); //當前目錄的子目錄：
                string[] rootFiles = Directory.GetFiles(dirRoot);        //當前目錄下的檔案：
                foreach (string s2 in rootFiles)
                {
                    if (s2.Contains(deleteFileName))
                    {
                        Console.WriteLine(s2);
                        File.Delete(s2);                      //刪除檔案
 

                    }
                }
                foreach (string s1 in rootDirs)
                {
                    DeleteFile(s1);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message.ToString());
            }
        }
 

使用：

 DeleteFile(filepath1);//為要刪除的檔案路徑（到父目錄）
