title: Converting string/*.rtf to PDF
body: <p>I have been trying to convert, both, a string and a .rtf document to a PDF document. So far I had mixed success. I have tried 3 different ways (code below) to turn the text into PDF. All of em compile, run and create a PDF, but in all casses the document ends up corrupted. 
  The error: <a href="https://www.dropbox.com/s/j7sckgwm10gf5ml/PdfError.jpg?dl=0" rel="nofollow">Link</a>

  <li><p>Turning a simple string into a PDF document</p>
  
  <pre><code>String msg = "dfsgfdsgdfgfdf";
  
  byte[] messageBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(msg);
  
  System.IO.FileStream stream = new System.IO.FileStream(@"C:\\file.pdf", System.IO.FileMode.CreateNew);
  System.IO.BinaryWriter writer = new BinaryWriter(stream);
  writer.Write(messageBytes, 0, messageBytes.Length);
  writer.Close();
  </code></pre></li>
  <li><p>Similar to method to method 1.:</p>
  
  <pre><code>//String myString: Contains the rft document loaded from the RTF file
  byte[] messageBytes = Encoding.UTF8.GetBytes(myString);
  System.IO.File.WriteAllBytes(@"C:\foo.pdf", messageBytes);
  </code></pre></li>
  <li><p>And the more complicated attempt 3:</p>

  <p>PS: In cases 2 and 3 I load a RTF document, which contains special (german) characters, in case 1. it is just the simple string you see in the code, yet it all ends up the same way (see image with the error above)</p>
  
  <p>I hope someone can help me or point me into the right direction.</p>
