c# 封装的文件夹操作类之复制文件夹

c#  封装的文件夹操作类之复制文件夹

一.复制文件夹原理：

1.递归遍历文件夹

2.复制文件

二.FolderHelper.cs

 /// <summary>
    /// 文件夹操作类
    /// </summary>
    public static class FolderHelper
    {
        /// <summary>
        /// 复制文件夹
        /// </summary>
        /// <param name="sourceFolderName">源文件夹目录</param>
        /// <param name="destFolderName">目标文件夹目录</param>
        public static void Copy(string sourceFolderName, string destFolderName)
        {
            Copy(sourceFolderName, destFolderName, false);
        }

        /// <summary>
        /// 复制文件夹
        /// </summary>
        /// <param name="sourceFolderName">源文件夹目录</param>
        /// <param name="destFolderName">目标文件夹目录</param>
        /// <param name="overwrite">允许覆盖文件</param>
        public static void Copy(string sourceFolderName, string destFolderName, bool overwrite)
        {
            var sourceFilesPath = Directory.GetFileSystemEntries(sourceFolderName);

            for (int i = 0; i < sourceFilesPath.Length; i++)
            {
                var sourceFilePath = sourceFilesPath[i];
                var directoryName = Path.GetDirectoryName(sourceFilePath);
                var forlders = directoryName.Split('\');
                var lastDirectory = forlders[forlders.Length - 1];
                var dest = Path.Combine(destFolderName, lastDirectory);

                if (File.Exists(sourceFilePath))
                {
                    var sourceFileName = Path.GetFileName(sourceFilePath);
                    if (!Directory.Exists(dest))
                    {
                        Directory.CreateDirectory(dest);
                    }
                    File.Copy(sourceFilePath, Path.Combine(dest, sourceFileName), overwrite);
                }
                else
                {
                    Copy(sourceFilePath, dest, overwrite);
                }
            }
        }
    }
