Question: Is there a function to remove the last cell from array?

it's a string array like: `{"a","b","c",""}`.

Answer: 
Erm... just resize it

```
 Array.Resize(ref theArray, theArray.Length -1);

```

From the docs

1. Create new array equal to existing array size -1
2. aNewArray = aOldArray

Ofcourse you could just null the last element in your array, but that would result in problems later. Otherwise, use a nice flexible list.
