title: ASP:ListBox Get Selected Items - One Liner?
body: <p>I am trying to get the selected items of an asp:ListBox control and put them in a comma delimited string. There has got to be a simpler way of doing this then:</p>
  
  <pre><code>foreach (ListItem listItem in lbAppGroup.Items)
  {
      if (listItem.Selected == true)
      {
          Trace.Warn("Selected Item", listItem.Value);
      }
  }
  </code></pre>
  
  <p>Is there a way to get this into one line? like my pseudo code here:</p>
  
  <pre><code>string values = myListBox.SelectedItems;
  </code></pre>
  
  <p>I am using ASP.NET and C# 3.5.</p>
  
  <p>Thanks for any help!!</p>
