When using the SQL Query, we could use the IN keyword to find the item something like this

SELECT * FROM MOVIES WHERE Movie_Name IN ('Thalaivaa', 'Jilla', 'Arrambam')

string[] CurrentName = new string[] { "Thalaivaa", "Jilla", "Arrambam" };

where CurrentName.Contains(u)

select u);

foreach (var item in selectedName)

Console.ReadLine();
