Question

I’m trying to do the equivelent of a SQL MINUS on two string arrays. Here’s the code that I’m trying to replicate:

        string returnValue = "";
        foreach (string eachWord in allWords)
        {
            foreach (string ignoreWord in ignoreWords)
            {
                if (eachWord != ignoreWord)
                {
                    returnValue += eachWord;
                }
            }
        }

I want to rewrite this as:

returnValue = allWords.Minus(ignoreWords);

or something equally succinct. I realize that behind the scenes I’ll end up with the same code, but I’m just being pedantic !

Answer 1

returnValue = allWords.Except(ignoreWords);
