C # Implementation of File operations encapsulation class full instance code sharing

This article mainly introduces the C # implementation of the file operation encapsulation class, combined with a complete instance of the C # Packaging file analysis of the deletion, movement, replication, renaming and other operations related implementation skills, the need for friends can refer to the next

This example describes the file operation encapsulation class implemented by C #. Share to everyone for your reference, as follows:

Recently found in the group share there is a C # file Operation Encapsulation class, which is done by invoking the Windows API to manipulate the deletion, movement, copying, and renaming of files. Download down a try, found really good, special in this record, in case of loss!

The file Operation class code is as follows:
