C # socket practice

I wrote a simple version of ftp (server and client). The running effect is as follows:

Click download to download the UI:

Principle: simulates the regular ftp mode and divides it into two socket connections: Text command socket and Data Channel socket.

Knowledge points involved:

• The thread calls the control on the main interface through invoke delegation.
• Subthread traversal stops when the program ends
• Blocking and synchronization between multiple threads
• Asynchronous Operation of socket transmission commands

The following functions are implemented:

• List all files in the home directory of the server
• Download files to the client (large files supported)

 

It is easy to implement and the code is downloaded here.
