How to create XML file from Dataset

XML is a tag based language, that means the document is made up of XML tags that contain information. We can create an XML file in several ways.

In the previous section we created an XML file using XmlTextWriter Class . Here we are creating an XML file Product.XML using an ADO.NET Dataset. In order to create this, we have to manually create a Datatable first and add the data of Product.XML in the Datatable . Then add the Datatable in a Dataset . Call the method WriteXml of Dataset and pass the file name Product.XML as argument.

using System;
using System.Data;
using System.Windows.Forms;
using System.Xml;

namespace WindowsApplication1
    public partial class Form1 : Form
        DataTable dt; 

        public Form1()

        private void button1_Click(object sender, EventArgs e)
            DataSet ds = new DataSet();
            dt = new DataTable();
            dt.Columns.Add(new DataColumn("Product_ID", Type.GetType("System.Int32")));
            dt.Columns.Add(new DataColumn("Product_Name", Type.GetType("System.String")));
            dt.Columns.Add(new DataColumn("product_Price", Type.GetType("System.Int32")));
            fillRows(1, "product1", 1111);
            fillRows(2, "product2", 2222);
            fillRows(3, "product3", 3333);
            fillRows(4, "product4", 4444);
            ds.Tables[0].TableName = "product";
            MessageBox .Show ("Done");

        private void fillRows(int pID, string pName, int pPrice)
            DataRow dr ;
            dr = dt.NewRow();
            dr["Product_ID"] = pID;
            dr["Product_Name"] = pName;
            dr["product_Price"] = pPrice;
