[转]C# 获取指定目录下所有文件信息、移动目录、拷贝目录

原文：http://blog.csdn.net/vchao13/article/details/6200255

１、获取指定目录下所有文件信息

1. /// <summary>
2. /// 返回指定目录下所有文件信息
3. /// </summary>
4. /// <param name="strDirectory">目录字符串</param>
5. /// <returns></returns>
6. public List<FileInfo> GetAllFilesInDirectory(string strDirectory)
7. {
8. List<FileInfo> listFiles = new List<FileInfo>(); //保存所有的文件信息
9. DirectoryInfo directory = new DirectoryInfo(strDirectory);
10. DirectoryInfo[] directoryArray = directory.GetDirectories();
11. FileInfo[] fileInfoArray = directory.GetFiles();
12. if (fileInfoArray.Length > 0) listFiles.AddRange(fileInfoArray);
13. foreach (DirectoryInfo _directoryInfo in directoryArray)
14. {
15. DirectoryInfo directoryA = new DirectoryInfo(_directoryInfo.FullName);
16. DirectoryInfo[] directoryArrayA = directoryA.GetDirectories();
17. FileInfo[] fileInfoArrayA = directoryA.GetFiles();
18. if (fileInfoArrayA.Length > 0) listFiles.AddRange(fileInfoArrayA);
19. GetAllFilesInDirectory(_directoryInfo.FullName);//递归遍历
20. }
21. return listFiles;
22. }

２、移动此目录到指定目录

1. /// <summary>
2. /// 从一个目录将其内容移动到另一目录
3. /// </summary>
4. /// <param name="directorySource">源目录</param>
5. /// <param name="directoryTarget">目的目录</param>
6. private void  MoveFolderTo(string directorySource, string directoryTarget)
7. {
8. //检查是否存在目的目录
9. if (!Directory.Exists(directoryTarget))
10. {
11. Directory.CreateDirectory(directoryTarget);
12. }
13. //先来移动文件
14. DirectoryInfo directoryInfo = new DirectoryInfo(directorySource);
15. FileInfo[] files = directoryInfo.GetFiles();
16. //移动所有文件
17. foreach (FileInfo file in files)
18. {
19. //如果自身文件在运行，不能直接覆盖，需要重命名之后再移动
20. if (File.Exists(Path.Combine(directoryTarget, file.Name)))
21. {
22. if (File.Exists(Path.Combine(directoryTarget, file.Name + ".bak")))
23. {
24. File.Delete(Path.Combine(directoryTarget, file.Name + ".bak"));
25. }
26. File.Move(Path.Combine(directoryTarget, file.Name), Path.Combine(directoryTarget, file.Name + ".bak"));
27. }
28. file.MoveTo(Path.Combine(directoryTarget, file.Name));
29. }
30. //最后移动目录
31. DirectoryInfo[] directoryInfoArray = directoryInfo.GetDirectories();
32. foreach (DirectoryInfo dir in directoryInfoArray)
33. {
34. MoveFolderTo(Path.Combine(directorySource, dir.Name), Path.Combine(directoryTarget, dir.Name));
35. }
36. }

３、拷贝此目录到指定目录

1. /// <summary>
2. /// 从一个目录将其内容复制到另一目录
3. /// </summary>
4. /// <param name="directorySource">源目录</param>
5. /// <param name="directoryTarget">目的目录</param>
6. static void CopyFolderTo(string directorySource, string directoryTarget)
7. {
8. //检查是否存在目的目录
9. if (!Directory.Exists(directoryTarget))
10. {
11. Directory.CreateDirectory(directoryTarget);
12. }
13. //先来复制文件
14. DirectoryInfo directoryInfo = new DirectoryInfo(directorySource);
15. FileInfo[] files = directoryInfo.GetFiles();
16. //复制所有文件
17. foreach (FileInfo file in files)
18. {              　
19. file.CopyTo (Path.Combine(directoryTarget, file.Name));
20. }
21. //最后复制目录
22. DirectoryInfo[] directoryInfoArray = directoryInfo.GetDirectories();
23. foreach (DirectoryInfo dir in directoryInfoArray)
24. {
25. CopyFolderTo(Path.Combine(directorySource, dir.Name), Path.Combine(directoryTarget, dir.Name));
26. }
27. }
