FileStream fs = new FileStream("products.xml", FileMode.Create); XmlWriter w = XmlWriter.Create(fs); w.WriteStartDocument(); w.WriteStartElement("products"); w.WriteStartElement ("product"); w.WriteAttributeString("id", "1001"); w.WriteElementString("productName", "Gourmet Coffee"); w.WriteElementString("productPrice", "0.99"); w.WriteEndElement(); w.WriteStartElement("product"); w.WriteAttributeString("id", "1002"); w.WriteElementString("productName", "Tea Pot"); w.WriteElementString("productPrice", "12.99"); w.WriteEndElement(); w.WriteEndElement(); w.WriteEndDocument(); w.Flush(); fs.Close();
We can write it also by using XmlTextWriter. the following is the sample code is using XmlTextWriter
// prepare and write XML document using (StringWriter writer = new StringWriter()) { using (XmlTextWriter doc = new XmlTextWriter(writer)) { // prepare XML header items doc.Formatting = Formatting.Indented; doc.WriteComment(”Summarized Incoming Call Stats”); doc.WriteStartElement(”contacts”); // join calls with contacts data foreach (Contact con in contacts) { if (callGroups.ContainsKey(con.Phone)) { List calls = callGroups[con.Phone]; // calculate the total call duration and average long sum = 0; foreach (CallLog call in calls) sum += call.Duration; double avg = (double)sum / (double)calls.Count; // write XML record for this contact doc.WriteStartElement(”contact”); doc.WriteElementString(”lastName”, con.LastName); doc.WriteElementString(”firstName”, con.FirstName); doc.WriteElementString(”count”, calls.Count.ToString()); doc.WriteElementString(”totalDuration”, sum.ToString()); doc.WriteElementString(”averageDuration”, avg.ToString()); doc.WriteEndElement(); } } doc.WriteEndElement(); doc.Flush(); doc.Close(); } Console.WriteLine(writer.ToString()); }
