通过 Twilio C# API 检索 SMS 对话伙伴列表

Question

I'm using the Twilio C# helper library in my SMS .NET project successfully, but I have a performance/optimization question:

Currently, in order to refresh my app's list of unique conversational partners, I'm basically returning a date-filtered list via MessageResource.Read like:

MessageResource.Read(dateSentAfter:=New DateTime(DatePart(DateInterval.Year, dtOldestMessageDate), DatePart(DateInterval.Month, dtOldestMessageDate), DatePart(DateInterval.Day, dtOldestMessageDate), 0, 0, 0))

...just so I can compile a list of the unique conversational partners by juggling/sorting the resulting list.

Given that I could have many messages to/from any/all partner(s), it seems rather inefficient.

Is there a method I'm missing that could simply return a list of unique conversational partners' phone numbers and the datetime of the last SMS (in or out) with them?

Below are the best practices for SMS logging, I would suggest maintaining the logs on your side/in your data store, rather than having Twilio store them and using the REST API to obtain them.
