How to read the last line in a textbox?

Question

I have a multiline textbox that constantly gets updated. I need to read only the last word/sentence in the textbox.

string lastLine = textBox1.ReadLine.Last(         


        

Answer 1

A textbox with the MultiLine property set to true has an array of Lines from which it is easy to extract the info required

int maxLines = textBox1.Lines.Length;
if(maxLines > 0)
{
    string lastLine = textBox1.Lines[maxLines-1];
    string lastWord = lastLine.Split(' ').Last();
}

A bit of caution here is needed. If your textBox still doesn't contain any lines you need to introduce a check on the number of lines present
