Introduction:

In this code you have to write the file name with the extension .xml and the code will create the xml file with that name and populate it.

Code:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.Xml.Serialization;
using System.Xml;
using System.IO;

public partial class ExportToXml : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ExportImportCS"].ConnectionString);
    protected void Page_Load(object sender, EventArgs e)
}

public void ConnectionXML()
{
    SqlCommand command = new SqlCommand();
    command.CommandText = "SELECT * FROM BookIssueDetails";
    command.CommandType = CommandType.Text;
    command.Connection = con;
    SqlDataAdapter da = new SqlDataAdapter(command);
    DataSet ds = new DataSet();
    da.Fill(ds, "BookIssueDetails");
    if (ds.Tables[0].Rows.Count > 0)
    {
        grdXML.DataSource = ds;
        grdXML.DataBind();
    }

    // Get a FileStream object
    StreamWriter xmlDoc = new StreamWriter(Server.MapPath("~/FileTest/Testdo.xml"), false);
    // Apply the WriteXml method to write an XML document
    ds.WriteXml(xmlDoc);
    xmlDoc.Close();
}

protected void btnExportToXml_Click(object sender, EventArgs e)
{
    ConnectionXML();
}
