读取XML文档结构并写入内容

            string initFileName = @"D:\Config.xml";

            DataSet ds = new DataSet();
            DataTable dt = new DataTable();
            System.Reflection.Assembly asm = Assembly.GetExecutingAssembly();
            ds.ReadXmlSchema(asm.GetManifestResourceStream("XMLSchema1.xsd"));
            dt = ds.Tables[0];
            DataRow dr = dt.NewRow();
            dr["UpdateIP"] = "192.168.0.101";
            dr["SoftWareName"] = "管理系统";
            dr["Version"] = "";

            dt.Rows.Add(dr);
            dt.AcceptChanges();
            dt.WriteXml(initFileName);//将DataTable中的内容写入到XML文件中
