How i Show DateTime in Label
<p>I have a <code>label</code>, a <code>textbox</code> and a <code>button</code> on a <code>form</code>. I want to add days to the current date/time. The value of days is connected to the <code>textbox</code> and the <code>datetime</code> is shown on the <code>label</code>.</p>

<pre><code>Double ce = Convert.ToDouble(textBox1.Text)
