C # copy files and copy folder instance code C # copy files

The original file path is fileoldpath;
New file path: filenewpath,
Then you can use
File. Move (fileoldpath, filenewpath)
Or file. Copy (fileoldpath, filenewpath)
Note that the path here is the folder path + file name, which can be implemented using path. Combine ().

C # copy a folder

The Directory class contains the createdirectory, move, and delete methods, but there is no copy method-_-. Below we will write a class for implementation, the idea is to recursively copy the files in the specified folder and Its subfolders to the target Folder:
