title: Get first file in directory
body: <p>This is probably pretty basic, but I'm trying to find out how I can find the first file in a directory? </p>
  
  <p>For example, if I've got these lines of code</p>
  
  <pre><code>Dim di as New IO.DirectoryInfo("C:\Test")
  Dim aryFi as IO.FileInfo() = di.GetFiles("*.txt")
  </code></pre>
  
  <p>I can see that the aryFi contains a list of all files, but I need only one and I need the full path of that one file. How can I get it?</p>
