原理：遍历当前文件夹的子文件，保存遍历文件夹下的所有文件
主要方法（2个）：
//获取文件夹下的所有文件 并保存 string[] path = Directory.GetFiles(NeedFilePath, "*.*"); //获取文件夹下的所有子文件 string[] files = Directory.GetDirectories(NeedFilePath);
代码如下：
1 /// <summary>
2 /// 文件递归
3 /// </summary>
4 /// <param name="NeedFilePath">需要转化的文件路径</param>
5 /// <param name="CopyToFilePath">指定生成的文件路径</param>
6 protected void CreatePath(string NeedFilePath, string CopyToFilePath)
7 {
8 string FilePath = CopyToFilePath;
9 if (!Directory.Exists(FilePath))
10 {
11 Directory.CreateDirectory(FilePath);
12 }
13 //获取文件夹下的所有文件 并保存
14 string[] path = Directory.GetFiles(NeedFilePath, "*.*");
15 string newfilepath = "";
16 int Count = 0;
17 foreach (string vale in path)
18 {
19 Count = 0;
20 Count = vale.Split(‘\\‘).Length;
21 newfilepath = FilePath + "\\" + vale.Split(‘\\‘)[Count - 1];
22 FileHelper.CreateFile(newfilepath);
23 FileHelper.FileCoppy(vale, newfilepath);
24 }
25 //获取文件夹下的所有子文件
26 string[] files = Directory.GetDirectories(NeedFilePath);
27 foreach (string vale in files)
28 {
29 Count = vale.Split(‘\\‘).Length;
30 //递归文件夹
31 CreatePath(vale, CopyToFilePath + "\\" + vale.Split(‘\\‘)[Count - 1]);
32 }
33 }
