title: Select and Print list of PDF files from a folder
body: <p>I have 2 issues 
  One: i have a list of reports numbers (elements) and the file path (_filePath) now when i use Directory.GetFiles() as per code below filtered based on elements list nothing returned,so may be something wrong with filtering this way, so kindly correct it.
  Two: please define the print code in foreach loop</p>
  
  <pre><code>// Print the selected files.
    private void PrintReports(Item _itemNo)
      {
          //GetNDEReportDirectory() return directory based on _itemNo
          string _filePath = GetNDEReportDirectory(_itemNo);
          List&lt;string&gt; elements = new List&lt;string&gt;();
          //GetNDEReportsList() return a list of required reports numbers
          elements = GetNDEReportsList(_itemNo);
  
          //option-2
          var files = Directory.GetFiles(_filePath).Where(f =&gt; 
                        elements.Contains(f)).ToList();
  
  
          foreach (var file in files)
          {
            //print code
  
          }
  
      }
  </code></pre>
