      uploadOptions.MimeType = "application/pdf"; 
      // Optional: set the name of the document, the same name as the file. 
      // This value is only important as a hint when the document file data does not contain a valid signature, such as TXT or XML files 
      uploadOptions.Name = "Leadtools.pdf";
