I need a c# parsing expert needed.
It needs to read a string paragraph and find phrases and words, that appear more than once.
string article = "the white rabbit is funny, the white rabbit lives in a cave. he eats carrots all day long. carrots are his favorite food.";
keywords kw = new keywords();
string[] list = [login to view URL](article);
the returned array should look like this
list[0] = the white rabbit|2
list[1] = white rabbit|2
list[2] = rabbit|2
list[3] = carrots|2
it should be smart enough to skip common words like, he, it, she, what, the, they, etc
but it will bring out phrases and keywords for the relevancy of the article.
