Quantshare support said

"In the script editor (Tools -> Script Editor), you can create a script that gets the symbols then add and remove them from the QuantShare database (using Symbols class). Scripts needs to be implemented in C#
You can automate script execution using (Tools -> Task Manager)"

but I'm not sure how to wget/curl my lists first in C#

I found this url
https://www.quantshare.com/sa-250-download-trading-data-using-the-url-script

but... no advice on how to download a file (curl or wget would be nice). The stackexchanges that detail how to do it in C# are not working (different libraries I assume)

https://stackoverflow.com/questions/9430960/c-sharp-make-wget-request?lq=1

These are my lists of symbols that are updated daily from nasdaq that I'd like to have redownloaded daily into quantshare

curl --silent "ftp://ftp.nasdaqtrader.com/SymbolDirectory/nasdaqlisted.txt" --stderr -> nasdaqlisted.txt
curl --silent "ftp://ftp.nasdaqtrader.com/SymbolDirectory/otherlisted.txt" --stderr -> otherlisted.txt

REM ETF Bonds
curl --silent "https://www.nasdaq.com/investing/etfs/etf-finder-results.aspx?download=Yes" --stderr -> ETFList.csv

What I'm hoping to do is download the 3 lists, then add the symbols into quantshare via a loop

Data is downloaded automatically given the URLs you provide. The URL-script tool allows you to add URLs dyncamically, from a list of symbols for example.
The scripts must be written in CSharp. In URL-script, there is already a ready to use function to get data from a URL:
string res = Functions.Net.DownloadString(url);

We really strongly suggest you check our documentation to understand how downloaders work.

"We really strongly suggest you check our documentation to understand how downloaders work. "

can you guide me in the right direction with a relevant url?

I have this which is pretty sparse

Where did you find this? I looked for a way to download a url in C# online (and provided the links), but I see you had this resource readily available. What I'm asking, is where is your resource?
