Question

Is there anyway to combine the 2 linq expressions into one? I.e. so one LINQ expression will return both the DistCount and the NormCount into the 2 separate int variables.

DistCount = (from string row in myList[i]
                where row.Length > 0
                select row).Distinct().Count();

NormCount = (from string row in myList[i]
                where row.Length > 0
                select row).Count();

Answer 1

do a group by row. You’ll then have the distinct count (# of groups) and the total (sum of Counts)

var q = (from string row in myList[i]
    where row.Length > 0
    group row by row into rowCount
    select new {rowCount.Key, rowCount.Count})

int distinct = q.Count();
int total = q.Sum(r=>r.Count);
