body: <p>I have a problem and I think you can help me I have this code:</p>
  
  <pre><code>string[] A1 = 
      Directory
          .GetFileSystemEntries(textbox2_f2.Text, "*", SearchOption.AllDirectories)
          .Select(System.IO.Path.GetFileName);
  
  for (int i1 = 0; i1 &lt; A1.Length; i1++)
      listbox_2f.Items.Add(A1[i1]);
  </code></pre>
  
  <p>And here is the error:  </p>
  
  <blockquote>
    <p>The type 'System.Collections.Generic.IEnumerable ' can not be
    implicitly converted to 'string []'. There is already an explicit
    conversion exists.</p>
