How to return the last element in a txt file C#

I have a text file that will basically be something like what is shown below. I would like to return just the last element if the first 2 element matches.

$fruit#color#type#smell#qty $fruit#color#type#smell#qty $fruit#color#type#smell#qty 

So this is what i kinda came up with. I would like to return the last element qty into result. Just wondering if it is possible to do it with an if else statement and how can i achieve it.

if (store.Contains(fruit+#+color))
             {
                  result=
             }
