Question

I am parsing my data output, however, my data has return charicters in it (\n). So when I run my code, the array is built and one of the arrays (4) is blank data… I have tried using null, “”, and ” “. Would anyone know how I can prevent that last array from showing?

        char[] returnChar= {'\n' };
        string parseText = captcha;
        string[] words = parseText.Split(returnChar);
        int count = words.Length;
        for (int i = 0; i < count; i++)
        {
            if (words[i] == null)
            {
                MessageBox.Show("This row is empty: " + i);
            }
                MessageBox.Show(words[i]);
        }

When doing String.Split, define the second parameter – StringSplitOptions.

string[] words = 
    parseText.Split(returnChar, StringSplitOptions.RemoveEmptyEntries);

This way it will skip over empty elements.
