XML Web Service to exposes the table from Database

By Akshay Teotia on Jan 12, 2012
Web Service are software program that use XML to exchange information with other software via common internet protocol. In simple sense, Web Services are means for interacting with objects over the Internet.


In this article I am going to make a XML Web service that exposes the Default table from a SQL Server database. For the basics of XML Web Service read my last article, click here.

First go through SQL Server and make a table.


Database- akshay

Table Name-member

Creating XML Web Service in .Net

Here is sample code which I use to create and consume ASP.NET Web Service:

Step 1 : Create the ASP.NET Web Service Source File

Open Visual Studio 2010 and create  a new web site.->Select .Net Framework 3.5. ->Select ASP.NET Web Service page -> Then, you have to give the name of your service. In this example I am giving it the name "mywebservice". Then Click the ok Button. A screen-shot of this activity is shown below.


Step 2 : Click on the "OK" button; you will see the following window:


Here (in the above figure), you will note that there is a predefined method "HelloWorld" which returns the string "Hello World". You can use your own method and can perform other operations. Here I made the simple method "Getmember" which returns the Dataset.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Data.SqlClient;
namespace mywebservice
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
        SqlConnection con;
        SqlDataAdapter adap;
        DataSet ds;
        public DataSet Getmember()
            con = new SqlConnection(@"Data Source=.;Initial Catalog=akshay;Persist Security Info=True;User ID=sa;pwd=wintellect;");
            adap = new SqlDataAdapter("select * from member", con);
            ds = new DataSet();
            adap.Fill(ds, "member");
            return ds;

Step 3 : Build Web Service and Run the Web Service for testing by pressing F5 function key.


Copy the url of this web service for further use.

Step 5 : click on Getmember button to test the web service.


Step 6 : Click on the Invoke button; you will see the following XML file.


Now our web service is ready to use; we just need to create a new web site to consume web service.

Example of Testing Web Service in .Net.

Step 7 : Create a Test Web Site by File > New > Web Site > ASP.Net Web Site.


Named the web site, for example here I have choosen name "Test".

Step 8 : Right Click Solution Explorer and Choose "Add Web Reference...":


Step 9 : Past the url of the web service and click on "Green arrow" button and then "Add reference".


Step 10 : Now your web service is ready to use In the Solution Explorer you will see.


Step 11 : Go to the Design of the Default.aspx page and drag and drop a button; rename it as "Show" and GridView (Inside data) as.


Step 12 : Go to the Default.cs page and for the button click event put the following code.

protected void Button1_Click(object sender, EventArgs e)
  localhost.Service mys = new localhost.Service();   // you need to create the object of the web service 
        GridView1.DataSource = 

 Step 13- Pressing the F5 function key to run the website, you will see:


Step 13 : Click on Show button.
