Question

How do you write out ‘AND’ and ‘OR’ in LINQ.
Ive tried the ‘AND’ keyword as well as ‘&&’ and a ‘,’.

I have also googled it and havent come across anything that helps.

Any help will be highly appreciated
Thanks

EDIT:

    int[] moreScores = new int[]{12,12,45,45,87,96};
int[] scores = new int[] { 97, 92, 81, 60 };
        // Define the query expression.
        IEnumerable<int> scoreQuery =
            from score in scores
    and moreScores
            where score > 80
            select score;

Answer 1

it depends on the langauge you use

in C#, && for AND and || for OR
in VB, AND for AND and OR for OR

now, what language are you using?

UPDATE 1

you want to join the two tables first right?

UNION method excludes duplicates from the return set.

IEnumerable<int> scoreQuery =  from score in (scores.Union(moreScores))
                               where score > 80
                               select score;
