WebBrowse 保存数据库word、

Hi,
This is an extended question to http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_23183926.html.
I have added a memorystream to a webbrowser:


        public WebBrowser createEmbeddedWord(Point point, MemoryStream memoryStream)
        {
            webBrowser = new WebBrowser();
            webBrowser.Location = point;
            Size size = new Size(new Point(200,200));
            webBrowser.Size = size;
           
            webBrowser.DocumentStream = memoryStream;
         
            return webBrowser;
                       
        }

And when I run the program it displays the text in the webbrowser control, but you can't edit the text and it doesn't give the embedded word (word opened in the webbrowser) as if I did : //webBrowser.Navigate(@"C:\Test\MainTest1.doc");
To test it I have written a small function which takes a document and inserts it into a byte[] to simulate the binary field on the server. Do I loose some formatting when I convert the document to byte[] since it doesn't open as a word document?

public class BLDocument
{
public byte[] OpenWord()
{
object missing = System.Reflection.Missing.Value;
bool Visible = false;
ApplicationClass WordApp = new ApplicationClass();
WordApp.Visible = Visible;
object filename = @"C:\MainTest1.doc";
Document adoc = WordApp.Documents.Open(ref filename, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing);
adoc.Activate();
adoc.ActiveWindow.Selection.WholeStory();
adoc.ActiveWindow.Selection.Copy();
IDataObject temp = Clipboard.GetDataObject();
string dataString = Convert.ToString(temp.GetData(DataFormats.UnicodeText));
UTF8Encoding enc8 = new UTF8Encoding();
byte[] dataArray = enc8.GetBytes(dataString);
//MemoryStream memorystream = new MemoryStream(dataArray);
return dataArray;
}
}
