怎样把用FileUpload控件上传的图片保存到数据库里？各位大虾帮帮小弟

protected   void   Button1_Click(   object   sender,   EventArgs   e   ) 

    { 

        System.IO.Stream   fileDataStream   =   FileUpload1.PostedFile.InputStream; 



        if   (fileDataStream.Length   <   1) 

        { 

            Msg.Text   =   "请选择文件。 "; 

            return; 

        } 



        //得到文件大小 

        int   fileLength   =   FileUpload1.PostedFile.ContentLength; 



        //创建数组 

        byte[]   fileData   =   new   byte[fileLength]; 

        //把文件流填充到数组 

        fileDataStream.Read(fileData,   0,   fileLength); 

        //得到文件类型 

        string   fileType   =   FileUpload1.PostedFile.ContentType; 



        //构建数据库连接，SQL语句，创建参数 

        string   strCnn   =   "Provider=Microsoft.Jet.OLEDB.4.0;Data   Source= "   +   Server.MapPath( "Image2Access.mdb "); 

        OleDbConnection   myConnection   =   new   OleDbConnection(strCnn); 

        OleDbCommand   command   =   new   OleDbCommand( "INSERT   INTO   Person   (PersonName,PersonEmail,PersonSex,PersonImageType,PersonImage) "   + 

        "VALUES   (@PersonName,@PersonEmail,@PersonSex,@PersonImageType,@PersonImage) ",   myConnection); 



        command.Parameters.AddWithValue( "@PersonName ",TextBox1.Text); 

        command.Parameters.AddWithValue( "@PersonEmail ",   "mengxianhui@dotnet.aspx.cc "); 

        command.Parameters.AddWithValue( "@paramPersonSex ",   "男 "); 

        command.Parameters.AddWithValue( "@PersonImageType ",   fileType); 

        command.Parameters.AddWithValue( "@PersonImage ",   fileData); 





        //打开连接，执行查询 

        myConnection.Open(); 

        command.ExecuteNonQuery(); 

        myConnection.Close();
