Convert WinWord Document to Blob

I have used a Winword Control to display the word document in a windows forms. Couple of my friends asked me how to save the document as a blob in to a database. So I thought of putting an article about it. The code is very Simple. Just use file system to convert the document to array of bytes[]

try
{
    //Delete the doc file used for Saving if already exists
    FileInfo mySaveFile = new FileInfo(@"C:\mysavefilename.doc");
    if (mySaveFile != null)
    {
        mySaveFile.Delete();
    }
    object overWriteExisting = false;
    object refMissing = Missing.Value;
    object saveFileName = _filenameSave;
    this.myWinWordControl.document.SaveAs(ref saveFileName, ref refMissing, ref refMissing, ref refMissing, ref refMissing, ref 
    refMissing,ref refMissing, ref refMissing, ref refMissing, ref refMissing, ref refMissing);
    //Show Blank document so that the current loaded file gets released
    ShowBlankDocument();
    //convert the doc file to blob.
    MyDS.mYRow row = null;
    FileStream fls;
    fls = new FileStream(_filenameSave, FileMode.Open, FileAccess.Read);
    //a byte array to read the doc
    byte[] blobDoc = new byte[fls.Length];
    fls.Read(blobDoc, 0, System.Convert.ToInt32(fls.Length));
    fls.Close();
    if (this._presenter.IsNewRecord)
    {
        _mYDS = new mYDS();
        row = _mYDS.MyTable.NewRow();
        row.MY_DOC = blobDoc;
        return _presenter.AddRecord(row);
    }
    else
    {
        row = mYDS.Rows[0];
        row.MY_DOC = blobDoc;
        return _presenter.UpdateRecord(row);
    }
}

catch (Exception exp)
{
    _ErrorWindow.Show(exp);
    return false;
}
 
The DataSet row conataining the blob can be saved with regular saving technique using Enterprise Libararies DAL.
