Comparing strings and arrays c#

Question

How would i go about making a function that would return true if a string contains any element of an array?

Something like this:

string str = "hi how are you";
string[] words = {"hi", "hey", "hello"};

would return true.

You can do it like this:

var array = new[] {"quick", "brown", "fox"};
var myString = "I love foxes.";
if (array.Any(s => myStr.IndexOf(s) >= 0)) {
    // One of the elements is there
}

This approach does not require that the element be a full word (i.e. the above fragment would return true, even though the word "fox" is not present there as a single word).
