Import of XML files in. net using (including creating XML and Importing XML)

The last time I talked about. net create XML file (a fixed way, a dynamic method), this time record how to import XML file

1. How to import XML files

1) XML file format

2) Style of form page

3) Source code Example

3.1) Create the source code for the XML file

         /// <summary>        ///Flexible mode Templates/// </summary>        /// <param name= "sender" ></param>        /// <param name= "e" ></param>        Private voidBtnmodel1_click (Objectsender, EventArgs E) {XmlTest OMS=NewXmlTest (); //get save XML nameOMs. Name = this. txt_model.text; //determine the XML values that the vendor holds            if( this. Rad_3shape. Checked) {oms. Factory= this. Rad_3shape.            Text; }            if( this. Rad_ruike. Checked) {oms. Factory= this. Rad_ruike.            Text; }            //determine the XML value saved in a compressed format            if( this. rad_3oxz. Checked) {oms.compress= this. rad_3oxz.            Text; }            if( this. Rad_zip. Checked) {oms.compress= this. Rad_zip.            Text; }            //determine the saved XML value            if( this. Rad_web. Checked) {oms. Upmethod= this. Rad_web.            Text; }            if( this. Rad_ftp.checked) {oms. Upmethod= this. rad_ftp.text; }            //MessageBox.Show ("manufacturer name:" +oms. Factory + ", compression format:" +oms.compress+ ", upload method:" +oms.            upmethod); //creating an XML Document ObjectXmlDocument xmldoc =NewXmlDocument ();            XmlText XmlText; //add a declaration paragraph to XMLXmlNode XmlNode = Xmldoc. Createxmldeclaration ("1.0","Utf-8",NULL); Xmldoc.            AppendChild (xmlnode); //Add a root element//Creating an element node modelXmlElement Xmlele = Xmldoc. CreateElement ("","Model",""); //Create a text nodeXmlText = Xmldoc. createTextNode (""); //Create a text node for an element nodeXmlele.            AppendChild (xmltext); //the binding element node belongs to the XML documentXmldoc.            AppendChild (xmlele); //Add a child elementXmlElement Xmlele1 = Xmldoc. CreateElement ("","Config",""); XmlText= Xmldoc. createTextNode (""); xmlele1.            AppendChild (xmltext); //Create an attribute node for an element nodexmlele1. SetAttribute ("ID","1"); //binding Element node config under ModelcofigXmldoc. Childnodes.item (1).            AppendChild (xmlele1); ////add A second child element            //XmlElement xmlele11 = Xmldoc.            createelement ("", "Config", ""); //xmltext = Xmldoc.            createTextNode ("configuration 2"); //xmlele11.            AppendChild (xmltext); //xmlele11.            SetAttribute ("id", "2"); //Xmldoc. Childnodes.item (1).            AppendChild (xmlele11); //to create a child element of the first child elementXmlElement Xmlele2 = Xmldoc. CreateElement ("","Factoryname",""); XmlText=Xmldoc. createTextNode (oms.            Factory); xmlele2.            AppendChild (xmltext); Xmldoc. Childnodes.item (1). AppendChild (xmlele1).            AppendChild (xmlele2); XmlElement Xmlele3= Xmldoc. CreateElement ("","Compressmethod",""); XmlText=Xmldoc.            createTextNode (oms.compress); xmlele3.            AppendChild (xmltext); Xmldoc. Childnodes.item (1). AppendChild (xmlele1).            AppendChild (xmlele3); XmlElement xmlele4= Xmldoc. CreateElement ("","Upmethod",""); XmlText=Xmldoc. createTextNode (oms.            upmethod); xmlele4.            AppendChild (xmltext); Xmldoc. Childnodes.item (1). AppendChild (xmlele1).            AppendChild (xmlele4); //save XML as File//determine if the saved path exists            if(! Directory.Exists (application.startuppath +@"\tempate") {directory.createdirectory (application.startuppath+@"\tempate"); }            //save XML as File (tempate under program Path)Xmldoc. Save (application.startuppath +@"\tempate\"+ Oms. Name +". XML"); MessageBox.Show ("Create"+oms. Name +". XML succeeded! ","Information Tip:"); //Xmldoc. Save (oms. name+ ". xml");}

3.2) Import the source code of the XML file

 <summary>///import template Method///</summary>//<param name= "sender" ></param>             <param name= "e" ></param> private void Btntempate_click (object sender, EventArgs E) {            OpenFileDialog Ofg = new OpenFileDialog (); Determine if the saved path exists if (!
