Question

I want to match common words between two strings

// C# code  
string str1,str2;

I want to check five words in the first fifteen words of string str1

str1="Musician Ben Sollee on the Ravages of Coal and the Wonders of the Bicycle"
str2="There is Wonders of Musician Ben Sollee on the Ravages of Coal"

I want to skip verb comparision from above strings like “of”, “on”, “the” etc.. only check words without verbs…

from above strings I want to compare str2 with str1 if it contain five duplicate words then give message it contains some duplicate words..

How I compare it and check it contains duplicates. I am happy with either a jQuery or C# answer.

One-liner Linq query for bonus points?

string[] str1Words = ...
string[] str2Words = ...
string[] dontCheck = {"of", "a", "the"};

var greaterThanFive = str1Words.Join(str2Words, s1 => s1, s2 => s2, (r1, r2) => r1)
                               .Distinct()
                               .Where(s => !dontCheck.Contains(s))
                               .Count() > 5;
