将文件复制到不同卷的递归方法

引言

由于我在.NET v1.1中没有找到将文件复制到另一个卷的方法，所以我自己创建了这个递归方法来实现它。

使用代码

这是FileUtilities类的代码，它定义了CopiarMoverDirectorio、CopiarDirectorio和MoverDirectorio方法。CopiarMoverDirectorio方法包含主要逻辑，其他两个是包装器。

using System;
using System.IO;

namespace RMORTEGA77.Utils
{
   public class FileUtilities
   {

      private static void CopiarMoverDirectorio(DirectoryInfo d, 
              string Destino, bool BorraOrigen, bool CreaDirVacios) 
      { 
         // Get files.
         FileInfo[] fis = d.GetFiles();
         // Create the directory destiny, if CreaDirVacios or contains files
         if ((fis.Length > 0) || (CreaDirVacios))
            Directory.CreateDirectory(Destino);
         foreach (FileInfo fi in fis) 
         { 
            fi.CopyTo(Destino + "\\" + fi.Name);
            // Delete the origin file if BorraOrigen
            if (BorraOrigen)
               fi.Delete(); 
         }
         // Recursive copy children dirs
         DirectoryInfo[] dis = d.GetDirectories();
         foreach (DirectoryInfo di in dis) 
         {
            CopiarMoverDirectorio(di,Destino + "\\" + di.Name, 
                                  BorraOrigen, CreaDirVacios); 
         }
         // Delete the origin dir if BorraOrigen
