c# - Look for words in strings with LINQ -

-

c# or vb.net suggestion welcome.

i have following code: 

 dim sometext = "stack on flow community"     dim someword = "over community"      if sometext.contains(someword)         response.write("word found.")     else         response.write("no word found.")     end if    function contains looks next words left right.   sometext.contains("over stack")  returns false sometext.contains("stack community")  returns false

i want of these return true long there words exist in string.

is there existing function cover case regardless of words position in string?

words.split(' ').any(sometext.contains)
