Now creating a new web application project in Visual Studio 2010. Now add the following namespace.

using System.Data.SqlClient;

using System.Data;

using System.Xml;


Now write the connection string to connect to the database.

 

string strConnection = "Data Source=.; uid=sa; pwd=wintellect;database=Rohatash;";

Let's take a closer look at using Generating XML files from SQL Database within the .NET Framework. Creating a new web application project in Visual Studio 2010. Drag and Drop a Button and Label control to the form and make a link in Label control to show the XML file. For a sample design your aspx page might be like this.

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Save" />

<asp:Label ID="LabelMessage" runat="server" ForeColor ="Red" Text="ShowMessage"></asp:Label>

 

In Codebehind write the following code on the Button Event. 

Codebehind 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Data.SqlClient;

using System.Data;

using System.Xml;

namespace WebApplication119

{

    public partial class WebForm1 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

 

        }

 

        protected void Button1_Click(object sender, EventArgs e)

        {

            SqlConnection con = new SqlConnection("Data Source=.; uid=sa; pwd=wintellect;database=Rohatash;");

            string strSQL = "Select UserId, UserName from UserDetail";

            SqlDataAdapter dt = new SqlDataAdapter(strSQL, con);

            DataSet ds = new DataSet();

            dt.Fill (ds,"UserDetail");

            ds.WriteXml(Server.MapPath("emp_xml_file.xml"));

           LabelMessage.Text = "<a href=emp_xml_file.xml> XML file</a>";

 

        }    

    }

}

 

Now run the application and test it.
