How to count the number of lines in a textbox?

Question

C++ / C#

I'm trying to count the number of lines in a text-box and display it in a lable
label9.Text = textBox2.Lines.Length;, but it says an error that it's impossible to convert int to string

Answer 1

label9.Text = textBox2.Lines.Length.ToString();
or

label9.Text = Convert.ToString(textBox2.Lines.Length);

Answer 2

:facepalm: :rtfm: .ToString
() though.
And yes, give the elements meaningful names, not textbox98 and btn56.
