title: Extract Embedded files from pdf using pdfbox in .NET application
body: <p>I am developing .NET Application using pdfbox to extract metadata, content and attached file from PDF.I was able to extract metadata and content, but stuck while extracting attached/embedded files.</p>
  
  <p>I have a pdf with embedded/attached doc file and want to retrieve that file.
  I have gone through the java example - <a href="http://svn.apache.org/repos/asf/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/ExtractEmbeddedFiles.java" rel="nofollow">http://svn.apache.org/repos/asf/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/ExtractEmbeddedFiles.java</a> . But while trying to use it in .Net, i got "non generic type 'java.util.Map' cannot be used with type arguments" in the following code snippet</p>
  
  <pre><code>java.util.Map&lt;String, COSObjectable&gt; names = efTree.getNames();
  </code></pre>
  
  <p>So, i will be grateful if anybody help me to extract the file from pdf.</p>
  
  <p>Thanks in advance.</p>
