I imagine you have a TextBox with the MultLine property enabled for true .

So, to get the content of the line where the vertical bar is positioned | just use this method that created PegaConteudoDaLinhaAtual() , see:

string PegaConteudoDaLinhaAtual(TextBox textBox)
{            
    var textoDaLinha = textBox.Lines[textBox.GetLineFromCharIndex(textBox.SelectionStart)].ToString();
    return textoDaLinha;           
}

Here is the implementation of it at the click of the button:

private void btnPega_Click(object sender, EventArgs e)
{            
    MessageBox.Show(PegaConteudoDaLinhaAtual(textBox1));
}
