Combinining several strings to a single string
<pre><code>    String f = DropDownList1.SelectedItem.Value;
    String s = DropDownList3.SelectedItem.Value.PadLeft(3,'0');
    String q = DropDownList2.SelectedItem.Value;
    String w = TextBox2.Text.ToString();
    String o = TextBox3.Text.ToString();
</code></pre>

<p>I want to combine it to a single string i.e <strong>String u= f+s+q+w+o</strong></p>

<p>How to do it?</p>
