问题描述

Hi, i have the following codes which allow me to save data into xml file. I have debug the codes and everything is ok, but the data wont appear in the xml file when i open it. Any idea on what has happened here?

XmlNode xRoot, xNode1, xNode2;
            XmlDocument xDoc = new XmlDocument();
            XmlDocument result = new XmlDocument();

            xRoot = xDoc.CreateElement("FTP_Information");
            

            try 
            {
                xNode1 = xDoc.CreateElement("Details");

                xNode2 = xDoc.CreateElement("FTP_ID");
                xNode2.InnerText = ID;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("FTP_Desc");
                xNode2.InnerText = desciption;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("File_Suffix");
                xNode2.InnerText = suffix;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("File_Name");
                xNode2.InnerText = filename;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("File_Prefix");
                xNode2.InnerText = prefix;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("Host");
                xNode2.InnerText = host;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("Port");
                xNode2.InnerText = port;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("UserID");
                xNode2.InnerText = enUser;
                xNode1.AppendChild(xNode2);

                xNode2 = xDoc.CreateElement("Password");
                xNode2.InnerText = enPassword;
                xNode1.AppendChild(xNode2);

                xRoot.AppendChild(xNode1);

                if (xRoot != null)
                {
                    result.LoadXml(xRoot.OuterXml);
                    // Save the document to a file and auto-indent the output.
                    XmlTextWriter writer = new XmlTextWriter("ftpSetup.xml", null);
                    writer.Formatting = Formatting.Indented;
                    result.Save(writer);
                    MessageBox.Show("Successful");
                }
            }
            catch(Exception ex)
            {
            }

什么是数据合约机制？

为什么不阅读呢？

要理解为什么我会建议它，而不是直接使用XML，请查看我过去的答案：

Why not reading about it?

Please see: http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

To understand why would I suggest it, instead of working with XML directly, please see my past answers:
Creating property files...[^],
How can I utilize XML File streamwriter and reader in my form application?[^].
