Dear Rick Shaub
Thank you so much.
Big help to me.
It works fine.

This is for symbol scanner, so i have to -1.
This is what i used to count lines include your 2 lines of coding.
string[] lines = textBox1.Text.Split('\n');
int numberOflines = lines.Length -1;
textBox2.Text = Convert.ToString(numberOflines);

Also, a more general solution would be to handle different types of newlines:

C#

int len = System.Text.RegularExpressions.Regex.Split("line1\r\nline2", @"\r?\n").Length;

Alternatively, you could use another version of string.Split:

C#

int len = "line1\r\nline2".Split(new string[] { "\r\n", "\n" }, StringSplitOptions.None).Length;

Solution 1

Can you post the code that's not working?

If you want the number of lines of text you could just use something like:

string[] lines = textbox1.Text.Split('\n');
int numberOflines = lines.Length;

Note: I'd just use Split('\n') because I've never seen '\r' use alone as a newline character. Additionally, Split('\n') will treat "\n" and "\r\n" identically.
