Question

The logic I’m trying to use is this:
1. Look at the last element of the List
2. If it is a new line (carriage return), delete it

        int stringLength = mailingList.Count;

        if (mailingList[stringLength - 1].Equals(Environment.NewLine))
        {
            //mailingList.RemoveAt(stringLength - 1);
            txtOutput.Text = "exists";
        }

        else
        {
            txtOutput.Text = "does not exist";
        }

But no matter what I use, I’m not able to get this to work.
I’ve also tried using:

if (mailingList[stringLength - 1] == "\r\n")

And this doesn’t work either.
From my output testing, I keep getting “does not exist”.

How do I identify whether the last element is a new line or not?

Any help would be great!

Thanks,

Answer 1

Well, then the last element probably isn’t a new line.

How to you get the lines?
Do you split a textbox? Then you won’t get new lines, you will get an empty string.
Then you should do something like:

if (string.IsNullOrWhiteSpace(mailingList.LastOrDefault())

What you likely should do before you take out the lines is to Trim the textbox text.
