C＃中的事务性文件管理

Question

I have a scenario in my application is that i need to upload some files (Zip files) from the client to the server and in the server i want to extract the Zip file and replace those files which i getting from extracting the Zip file into some other folder.

The files which i need to be replaced is mostly dll files. So one thing that i need to ensure that either all files should be replaced or none of them get replaced.

Is there any way in C# to achieve this (like Transaction in SQL) ? If anything bad occurs while replacing files (Example: no memory space), every changes happened to the previous files should be rollbacked.

Hope you understand the problem.

Any help ?

Having a quick poke around, only way I can see you doing this would be through https://msdn.microsoft.com/en-us/magazine/cc163388.aspx which involves some native code. Otherwise you could use a third party tool such as http://transactionalfilemgr.codeplex.com/

If you wanted to manage it yourself or go for a simpler approach, I would suggest backing up the existing files somewhere before trying to copy the new files. This could be in another folder or zipped up. Then if the copy fails, you handle this and revert all the files to their original state.

Whatever you choose, make sure you have plenty of logging so you can see what's happening and if/when something goes wrong :)
