                    objFileStream.Read(tmpImage, 0, objFileStream.Length)
                    buffersize = objFileStream.Length
                    picPhoto.Image = Image.FromStream(objFileStream)                    Dim xw As New Xml.XmlTextWriter("c:\TempXmlX.xml", Encoding.UTF8)
                    xw.WriteStartDocument()
                    xw.WriteStartElement("root")
                    xw.WriteBase64(tmpImage, 0, tmpImage.Length)
                    objFileStream.Close()
                    xw.WriteEndElement()
                    xw.WriteEndDocument()
                    xw.Flush()

存盘string strImgFile = "c:\\222.jpg";
string strXmlFile = "c:\\222.xml";FileStream fs = new FileStream(strImgFile, FileMode.Open, FileAccess.Read);
byte[] bytes = new Byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
XmlTextWriter tw = new XmlTextWriter(strXmlFile, System.Text.Encoding.UTF8);
tw.WriteStartDocument();
tw.WriteStartElement("root");
tw.WriteBase64(bytes, 0, bytes.Length);
tw.WriteEndElement();
tw.WriteEndDocument();
tw.Flush();
tw.Close();
