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 = ; i < sourceFilesPath.Length; i++)
             {
                 var sourceFilePath = sourceFilesPath[i];
                 var directoryName = Path.GetDirectoryName(sourceFilePath);
                 var forlders = directoryName.Split('\\');
                 var lastDirectory = forlders[forlders.Length - ];
                 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);
                 }
             }
         }
     }
