Create XML File using C#

Submitted by donbermoy on Wednesday, June 18, 2014 - 07:47.

Today in C#, I’m going to teach you how to create a program that also creates an XML file using C#. We all know that XML (Extensible Markup Language) is an easy way to create common information formats and share both the format and the data on the World Wide Web or elsewhere. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application in C# for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application and name your program as XMLSample. 2. Next, add only one Button named Button1 and labeled it as "Create XML". You must design your interface like this: design

3. Import System.Xml namespace to access all the xml class.

using System.Diagnostics;
using System;
using System.Windows.Forms;
using System.Collections;
using System.Drawing;
using System.Data;
using System.Collections.Generic;
 
 
using System.Xml;

4. Create a method named createNode that has this parameters (string pID, string pName, string pPrice, XmlTextWriter writer). The XmlTextWriter class here is used to write xml file.

private void createNode(string pID, string pName, string pPrice, XmlTextWriter writer)
                {
            // write Product as a Start Element
                        writer.WriteStartElement("Product");
            // write Product_id as a Start Element as a content of Product
                        writer.WriteStartElement("Product_id");
            // write a string for Product_id 
                        writer.WriteString(pID);
            // end the element of Product_id using /
                        writer.WriteEndElement();
            // write Product_name as a Start Element as a content of Product
                        writer.WriteStartElement("Product_name");
            // write a string for Product_name 
                        writer.WriteString(pName);
            // end the element of Product_name  using /
                        writer.WriteEndElement();
            // write Product_price as a Start Element as a content of Product
                        writer.WriteStartElement("Product_price");
            // write a string for Product_price
                        writer.WriteString(pPrice);
            // end the element of Product_price using /
                        writer.WriteEndElement();
            // end the element of Product using /
                        writer.WriteEndElement();
                }

5. For Button1 for writing an XML File, put this code below.

                public void Button1_Click(System.Object sender, System.EventArgs e)
                {
            // instatantiate XmlTextWriter that the file name of the xml file will be product.xml
                        XmlTextWriter writer = new XmlTextWriter("product.xml", System.Text.Encoding.UTF8);
            // set WriteStartDocument to true
                        writer.WriteStartDocument(true);
            // the xml formatting has indention
                        writer.Formatting = Formatting.Indented;
            // 2 indentions
                        writer.Indentation = 2;
            // Make now the first element into "Table"
                        writer.WriteStartElement("Table");
            // we will use the createNode method with the parameters of product id, product name, product price, and the writer variable for  XmlTextWriter
                        createNode("1", "Product 1", "1000", writer);
                        createNode("2", "Product 2", "2000", writer);
                        createNode("3", "Product 3", "3000", writer);
                        createNode("4", "Product 4", "4000", writer);
            // end the element with the word table and using /
                        writer.WriteEndElement();
            // end the file
                        writer.WriteEndDocument();
            //close the file
                        writer.Close();
                }
