StreamReader to read word file-(output-Strange Characters)

[Newface]

I am trying to read a word file and display it in a panel.
my idea is like below,which is not providing correct output:

protected void cmdView_Click(object sender, EventArgs e)
    {    
//ReadWriteData is a class   
        ReadWriteData rwd = new ReadWriteData();
        string sb = rwd.ReadFile(@"C:\Documents and Settings\pa_mukeshk\My Documents\Visual Studio 2008\Execute 1.0.docx");
        Session["FileData"] = sb;
        Response.Redirect("~/HomePages/ViewPage.aspx", true);
//ReadWriteData class has below method
public string ReadFile(string path)
    {
        FileStream fstream = new FileStream(path, FileMode.Open, FileAccess.Read);
        StreamReader sreader = new StreamReader(fstream, System.Text.Encoding.UTF8);
        string sr = sreader.ReadToEnd();
        return sr;
    }
//on the load of ViewPage.aspx,i have
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string sb = (string)Session["FileData"];
            Label lt = new Label();
            lt.Text = sb.ToString();
            myPanel.Controls.Add(lt);
        }
    }
