//給Excel檔案添加"Everyone,Users"使用者組的完全控制許可權  FileInfo fi = new FileInfo(excelPath);  System.Security.AccessControl.FileSecurity fileSecurity = fi.GetAccessControl();  fileSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));  fileSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));  fi.SetAccessControl(fileSecurity);    //給Excel檔案所在目錄添加"Everyone,Users"使用者組的完全控制許可權  DirectoryInfo di = new DirectoryInfo(Path.GetDirectoryName(excelPath));  System.Security.AccessControl.DirectorySecurity dirSecurity = di.GetAccessControl();  dirSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));  dirSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));  di.SetAccessControl(dirSecurity);
