Checking if a string(1) is empty or notthe

[DevilCult]

Hello i'm having some difficulty with this problem. I'm getting a list of word from a textbox wich look like this: Whatever#2, word, is, there
Then im splitting up that line with the , identifier and put it in a array lets say x(). Now i have another array named y() which gonna resplit each word with the identifier "#"
so in the final i have an array named y(0) which contain the word and sometime y(1) which contain a number. But when i try to check with an if statement if y(1) is nothing i get an IndexOutofRangeException because there is nothing in it... I know there is nothing but how to check it in code please? I'm confused.

Thanks for reply!

There's no point checking for Nothing because it can't possibly be Nothing. If there is a # in the initial value then the resulting array will have two elements and the second element will be an empty String. If there is no # in the initial value then the resulting array will only have one element. That's why you get an IndexOutOfRangeException: there is no element at index 1. So, first you need to test the length of the array and, if there is a second element, test whether it is an empty String.
