Transfer files in using c#

Question

如何使用c＃将文件从文件夹复制到另一个文件夹？

Answer 1

Here is a good example from MSDN:

How to: Copy, Delete, and Move Files and Folders (C# Programming Guide)

Answer 2

The System.IO.File, System.IO.Directory, System.IO.FileInfo classes "Mr.Expert" suggested above are fine for copying and deleting individual files.

But if you are deleting/copying large number of files you are probably better off using an alternative method see this question I asked previous..

Delete a large number (>100K) of files with c# whilst maintaining performance in a web application?

The System.IO.Directory.GetFiles can cause a performance issue when dealing with large number of files.

Answer 3

System.IO.File.Copy
