c# LINQ joining to comma separated string

Question

I have a string of comma separated values called driverids.

Should I use the comma separated list or the array that this comma separated list comes from to use this in a join.
How would I use a join in linq to these driverids?

_currentDriverData.AddRange(elementsCurrent.Join(driverids)

// gets distinct driver ids from the driver duty status change logs;
string driverids = string.Join(",", _logsDutyStatusChange
                         .Select(item => item.did)
                         .Distinct()
                         .ToArray());

//gets all current driver information
//_currentDriverData.AddRange(elementsCurrent.Where(drivers)

_currentDriverData.AddRange(elementsCurrent.Join(driverids).Select.........

What are you trying to join them to?

You would do something like this (assuming _currentDriverData us a list of ids):

_currentDriverData.AddRange(commaSeparatedString.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyElements).ToList());
