Dynamically generate book information XML files from C #

Dynamically generate the book information XML file (books.xml) through C #, with the following file:

<?xml version= "1.0" encoding= "iso-8859-1"?>   <bookstore>     <book id= "1" category= "Children" >   <title>harry potter</title>   <author>j K. rowling</author>   < publishdate>2005-08-15</publishdate>   <price>29.99</price>   </book>     < Book id= "2" category= "WEB" >   <title>learning xml</title>   <author>erik T. Ray</author >   <publishDate>2003-10-18</publishDate>   <price>39.95</price>   </ Book>     </bookstore>

Method 1: Use StringBuilder to stitch the XML

<summary>///create book information XML///</summary> public void Createbookxml (string fileName) {StringBuilder Xmlresul t = new StringBuilder ("<?xml version=\" 1.0\ "encoding=\" utf-8\ "?>"); List<bookinfo> Booklist = Getbooklist ();  Gets the list of books if (Booklist! = null && booklist.count > 0) {xmlresult.append ("<bookstore>"); foreach (BookInfo Book in Booklist) {Xmlresult.appendformat ("<book id=\"} {0}\ "category=\" {1}\ ">", Book. BookId, book. Category); Xmlresult.appendformat ("<title>{0}</title>", book. Title); Xmlresult.appendformat ("<author>{0}</author>", book. Author); Xmlresult.appendformat ("<publishDate>{0}</publishDate>", book. Publishdate.tostring ("Yyyy-mm-dd")); Xmlresult.appendformat ("<price>{0}</price>", book. Price); Xmlresult.append ("</book>"); } xmlresult.append ("</bookstore>"); }//write to file try {//1. create file stream FileStream FileStream = new FileStream (FileName, FileMode.Create);//2. Create writer StreamWriter sTreamwriter = new StreamWriter (fileStream); 3. Write content to file Streamwriter.writeline (Xmlresult); 4. Turn off the writer StreamWriter.Close (); 5. Close file stream filestream.close (); } catch (Exception e) {}}

Method 2: Create XML using the XmlTextWriter class

<summary>//create book information XML///</summary>//<param name= "fileName" ></param> public void Create Bookxml (string filename) {try {FileStream FileStream = new FileStream (FileName, FileMode.Create); XmlTextWriter writer = new XmlTextWriter (FileStream, Encoding.UTF8); List<bookinfo> Booklist = Getbooklist (); Get a list of books if (Booklist! = null && booklist.count > 0) {writer. WriteStartDocument (); Writer. WriteStartElement ("bookstore"); Create a parent node foreach (BookInfo book in Booklist) {writer. WriteStartElement ("book"); Create a child node writer. WriteAttributeString ("id", book.) Bookid.tostring ()); Add property writer. WriteAttributeString ("category", book.) Category); Book name node writer. WriteStartElement ("title"); Writer. WriteValue (book. Title); Node assignment writer. WriteEndElement (); Book author node writer. WriteStartElement ("author"); Writer. WriteValue (book. Author); Writer. WriteEndElement (); Publishing Time node writer. WriteStartElement ("Publishdate"); Writer. WriteValue (book. Publishdate.tostring ("Yyyy-mm-dd")); Writer. WriteEndElement (); Sales price node writer. WriteStartElement ("Price"); Writer. WriteValue (book. Price); Writer. WriteEndElement (); Writer. WriteEndElement (); Child node End} writer. WriteEndElement (); Parent node End} writer. WriteEndDocument (); Writer. Close (); Filestream.close (); } catch (Exception e) {}}

XmlTextWriter class: A writer that provides a fast, non-cached, forward-only method that generates a stream or file that contains XML data.
WriteStartDocument () method: writes the declaration of the XML.
WriteEndDocument () method: Closes any open elements or attributes and sets the writer back to the Start state.
WriteStartElement (String localname) method: Creates the start of a node.
WriteAttributeString (String localname, String value) method: Adds a property to the node.
WriteValue (Value) method: Assigns a value to a node.

3, other code

3.1 get book list

<summary>///Get a list of books///   </summary>/   <returns></returns>   public List <BookInfo> getbooklist ()   {   list<bookinfo> Booklist = new list<bookinfo> ();   BookInfo Book1 = new BookInfo () {   BookId = 1,   Category = "Children",   Title = "Harry Potter",   Author = "J K. Rowling ",   publishdate = new DateTime (2005,08,15), Price   = 29.99   };   Booklist.add (BOOK1);   BookInfo book2 = new BookInfo ()   {   BookId = 2,   Category = "WEB",   Title = "Learning XML",   Author = "Erik T. Ray",   publishdate = new DateTime (2003,10,18), Price   = 39.95   };   Booklist.add (BOOK2);   return booklist;   }

3.2 Book Information entity class

<summary>////   Library Information entity class///   </summary> public   class BookInfo   {public   int BookId { Set Get }//Book ID public   string Title {set; get;}//Book name public   string category {set; get;}//Book category public   string Au Thor {set; get;}//Book author public   DateTime publishdate {set; get;}//Publication time public   Double price {set; get;}//Sales Prices Lattice   }

The above is through the C # dynamic generation of book information XML file content, more relevant content please pay attention to topic.alibabacloud.com (www.php.cn)!
