Line 419: Null Reference Exception on empty cells

[basicbear]

I used the old code ("theCell != null") and got null reference exceptions when cells were empty.

I found that theCell.InnerText.Length>0 avoided the null reference exception. Using Object.ReferenceEquals(), or !(x== null) didn't change the outcome.
