Exclude list items that contain values from another list

// Contains four values.
int[] values1 = { 1, 2, 3, 4 };

// Contains three values (1 and 2 also found in values1).
int[] values2 = { 1, 2, 5 };

// Remove all values2 from values1.
var result = values1.Except(values2);

var results = dataset.Where(i => !excluded.Any(e => i.Contains(e)));

Try:

var result = from s in dataset
             from e in excluded 
             where !s.Contains(e)
             select e;
