C#

// operator AND has precedence over OR operator, parenthesis are needed
dataView.RowFilter = "City = 'Tokyo' AND (Age < 20 OR Age > 60)";

// following examples do the same
dataView.RowFilter = "City <> 'Tokyo' AND City <> 'Paris'";
dataView.RowFilter = "NOT City = 'Tokyo' AND NOT City = 'Paris'";
dataView.RowFilter = "NOT (City = 'Tokyo' OR City = 'Paris')";
dataView.RowFilter = "City NOT IN ('Tokyo', 'Paris')";

These are the basic examples of DataView.Rowfilter
