如何从 .NET 应用程序中的 FTP 协议获取目录文件大小

问题描述

I am currently making a small .NET console application to do an automateed backup of some of my files onto my server. The issue that I am running into is that I've had some bad weather on my end which led to some power and network outages. During this time I noticed that a good portion of my files didn't go through or got corrupt. I was wondering if there was a way to get a size of the folder on the other end and see if the file names, number of files, and total directory size match up. I've tried WinSCP and NcFTP as ways to transfer files over, but I haven't seen anything regarding getting a proper filesize.

This is pretty much a windows to windows transfer so if there is a command line argument that gives me back a size through the FTP client that would be great.

There is no standard way to request "total size of files in this directory". You can ask for each file size individually via SIZE file.txt, or you can ask for ls -l of an entire directory and parse the file sizes out.
