In this case, the content of the objdata is a Compound File. You can spot the famous 'd0cf11e0' header (looks like "docfile"). More on this here: Developing a tool to recognise MS Office file types ( .doc, .xls, .mdb, .ppt ).

I have written a small example that you can use to extract the data. You can use it like this:

        string ole = "2090_Object_Text_0.ole"; // your file
        string text = File.ReadAllText(ole);
        DocFile.Save(text, "mydoc.doc"); // you should adapt this depending on the object class (Word.Document.8 is a .doc).

And the DocFile helper code:

public static class DocFile
{
    // magic Doc File header

    private const string Header = "d0cf11e0";

    public static void Save(string text, string filePath)
    {
        if (text == null)
            throw new ArgumentNullException("text");

        if (filePath == null)
            throw new ArgumentNullException("filePath");

        int start = text.IndexOf(Header);
        if (start < 0)
            throw new ArgumentException(null, "Text does not contain a doc file.");

        int end = text.IndexOf('}', start);
        if (end < 0)
        {
            end = text.Length;
        }

        using (MemoryStream bytes = new MemoryStream())
        {
            bool highByte = true;
            byte b = 0;
            for (int i = start; i < end; i++)
            {
                char c = text[i];
                if (char.IsWhiteSpace(c))
                    continue;

                if (highByte)
                {
                    b = (byte)(16 * GetHexValue(c));
                }
                else
                {
                    b |= GetHexValue(c);
                    bytes.WriteByte(b);
                }
                highByte = !highByte;
            }
            File.WriteAllBytes(filePath, bytes.ToArray());
        }
    }

    private static byte GetHexValue(char c)
    {
        if (c >= '0' && c <= '9')
            return (byte)(c - '0');

        if (c >= 'a' && c <= 'f')
            return (byte)(10 + (c - 'a'));

        if (c >= 'A' && c <= 'F')
            return (byte)(10 + (c - 'A'));

        throw new ArgumentException(null, "c");
    }
