QueryOptions ignored when getting calendar events in MSGraph Dot Net

Question

I'm trying to get the user's calendar events for today. So I added some query parameters but they're getting ignored and the graph client returns the user's events as if I didn't supply any parameters (startatetime):

var options = new QueryOption[]
{
    new QueryOption("startdatetime", DateTime.UtcNow.ToString("o")),
    new QueryOption("enddatetime", DateTime.UtcNow.AddDays(1).ToString("o")),
};
var events = await graphServiceClient
    .Me
    .Calendar
    .Events
    .Request(options)
    .GetAsync();

I tested it in the graph explorer and it works fine. But in the sdk, it returns calendar events that started before today.

Your code is the equivalent of calling:

`/events?startdatetime={dateTime}&enddatetime={dateTime}`. 

That is a valid endpoint, but you're passing invalid query params. What you're looking for is calendarView:

`/calendarView?startdatetime={dateTime}&enddatetime={dateTime}`

Using the SDK, this would look like this:

var options = new QueryOption[]
{
    new QueryOption("startDateTime", DateTime.UtcNow.ToString("o")),
    new QueryOption("endDateTime", DateTime.UtcNow.AddDays(1).ToString("o")),
};

var events = await graphServiceClient
    .Me
    .CalendarView
    .Request(options)
    .GetAsync();
