title: How to use a DropDown to load and open files?
body: <p>I have a method in my BusinessLayer. The result of this method is a variable of type <code>IEnumerable&lt;string&gt;</code> and is returning me a list of filenames that are matching a description. How can I make all these files to be displayed in WinForms DropDown, and then when I click on a file name to open it?</p>
  
  <p>Here is the method for locating the files:</p>
  
  <pre><code>public IEnumerable&lt;string&gt; GetFilesByInfSite()
  {
      var files = Directory.EnumerateFiles(@"path...").
                  Select(f =&gt; Path.GetFileName(f));
      return files;
  }
  </code></pre>
  
  <p>If necessary I can show the code for Deserialization.</p>
