title: ListView CheckedItems find item by name
body: <p>I need to check if an item with a particular name exists in the CheckedItems collection of a ListView. </p>
  
  <p>So far I've tried:</p>
  
  <pre><code>ListViewItem item = new ListViewItem(itemName);
  
  if (listView1.CheckedItems.IndexOf(item) &gt;= 0)
     return true;
  </code></pre>
  
  <p>and </p>
  
  <pre><code>ListViewItem item = new ListViewItem(itemName);
  
  if (listView1.CheckedItems.Contains(item))
     return true;
  </code></pre>
  
  <p>Neither of those worked. Is there a way to do this without looping through CheckedItems and checking them one by one?</p>
