C# textBox1 Line count shows in textBox2. no counting for pure enter key(just Enter Key without value)

See more:

C#

in CheckKeys function
textBox1 is text input
content of text lines go to array
textBox2 is total line numbers.


Whenever user input text and press "Enter Key"
textBox2 shows total line numbers.

Problem is , When user input Enter key without text,
"Enter Key" still count as lines.

Is there way to find out textBox1 line input is empty ?
and break from if statement(no count for Enter Key only lines) ?

I tried create inside if statement,
but it only allow one time "Enter Key" as 0 count.
When i try next line with "Enter Key", it still count as line.

any help will be appreciated.
Thanks


private void CheckKeys(object sender, KeyPressEventArgs e)
{
string[] a = null;
if (e.KeyChar == (char)13)
{
a = textBox1.Text.Split('\n');
textBox2.Text = Convert.ToString(i);
}

}


Solved problem
Above code was fine
forgot to use e.Handle .
If statement can have many if statement inside.
Program works fine.

e.Handle = flase; --> will process following lines
e.Handle = true; --> exit e.Handle function
Try to use { } even it has only 1 line.

I searched codeproject to fix my problem,
I had hard time to figure it out.

There are some nice people in codeproject.com who give his fancy code,
some just talking and talking.

Thanks guys.
