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

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

Answer: 
The length of an array is immutable, but you can create a new array without the empty `""` strings:

```
string[] newArray = myArray.Where(str => str != "").ToArray();

```
```
var newArraySize = oldArray.Length - 1;
var newArray = new string[newArraySize];
Array.Copy(oldArray, newArray, newArraySize);

```
