List的使用

 List<string> AllFilesPath = new List<string>();
                if (filesOrDirectoriesPaths.Length > 0) // get all files path
                {
                    for (int i = 0; i < filesOrDirectoriesPaths.Length; i++)
                    {
                        if (File.Exists(@strZipTopDirectoryPath + filesOrDirectoriesPaths[i]))
                        {
                            AllFilesPath.Add(strZipTopDirectoryPath + filesOrDirectoriesPaths[i]);
                        }
                        else if (Directory.Exists(@strZipTopDirectoryPath + filesOrDirectoriesPaths[i]))
                        {
                            GetDirectoryFiles(filesOrDirectoriesPaths[i], AllFilesPath);
                        }
                    }
                }
