I have my own implementation, and it works very well.

    /// 

    /// Read a PDF file and returns the string content.
    /// 
    /// ByteArray, MemoryStream or URI
    /// FileContent.
    public static string ReadPdfFile(object par)
    {
        if (par == null) throw new ArgumentNullException("par");

        PdfReader pdfReader = null;
        var text = new StringBuilder();

        if (par is MemoryStream)
            pdfReader = new PdfReader((MemoryStream)par);
        else if (par is byte[])
            pdfReader = new PdfReader((byte[])par);
        else if (par is Uri)
            pdfReader = new PdfReader((Uri)par);

        if (pdfReader == null)
            throw new InvalidOperationException("Unable to read the file.");

        for (var page = 1; page <= pdfReader.NumberOfPages; page++)
        {
            var strategy = new SimpleTextExtractionStrategy();
            var currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);
            currentText = Encoding.UTF8.GetString(Encoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(currentText)));
            text.Append(currentText);
        }

        pdfReader.Close();

        return text.ToString();
    }
