C# code to count number of lines in textbox ?

Hehehe

He is asking in asp.net and some are copying and pasting code from stack overflow. For your kind information that code will work in windows form application only not in asp.net

Try this

string[] lines = [TextBox_ID].Text.Split(new Char[] { '\n' }, StringSplitOptions.RemoveEmptyEntries);
int count = lines.Length;

Hi Rajavel,

Using it is simple if you use LINQ.

int numberOfLine = textBox1.Lines.Count();

You can also do this in a shorter way using LinQ. To count the lines and exlcude the last line if it is empty:

var lines = tb.Lines.Count();
lines -= String.IsNullOrWhiteSpace(tb.Lines.Last()) ? 1 : 0;

And to count only non-empty lines:

var lines = tb.Lines.Where(line => !String.IsNullOrWhiteSpace(line)).Count();

Hi,

You can use the below code.

string strtext = textbox1.Text;
var textArr = strtext.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
txtline.Text = textArr.Length.ToString();
