Q:

Microsoft Graph CSharp SDK and filtering - how to construct a call to filter on CreatedDateItem? 

I am coding against the Microsoft Graph CSharp SDK and I am trying to proof out the ability to filter DriveItems on the CreatedDateTime.  
I am aware that if I construct a call like:
await graphServiceClient. Drives["user@user.onmicrosoft.com"].Root. Request().GetAsync();
Will return all the metadata, however, I wanted to know if there was a way to construct a call where it would filter on the CreatedDateTime within a single call, is this possible?  

A:

You can apply Select, Filter, etc.  query options to your request as long as the underlying Graph API method supports it.  It is a bit hidden but this is documented in the wiki. 
await graphServiceClient.Drives["user@user.onmicrosoft.com"]
    .Root
    .Request()
    .Filter(...)
    .GetAsync();
