4. WEBSERVICE PROGRAM

Step 1 and 2

Service.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Services;

[WebService(Namespace = "http://tempuri.org/")]

[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 Service : System.Web.Services.WebService

{

[WebMethod]

public int Multiplication(int a,int b)

{

return (a*b);

}

Service.asmx-

<%@ WebService Language="C#" CodeBehind="~/App_Code/Service.cs" Class="S

ervice" %>

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.

Click on the Multiplication button to test the web service.

Enter the value of a and b.

By pressing the "Invoke" button a XML file is generated.

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

the web service.

Example of Testing Web Service in .Net.

Step 5- Create a Test Web Site by File > New > Web Site > Asp.net Web Site

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

Step 6- Right-click Solution Explorer and choose "Add Web Reference".

Step 7- Paste the URL of the web service and click on 'Go' button and then 'Add

reference'.

Step 8- Now your web service is ready to use in the Solution Explorer you will see.

Step 9- Go to the design of the Default.aspx page; drag and drop three Textboxes and one

button.

Step 10- Go to Default.cs page and on the button click event use 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

int a = Convert.ToInt32(TextBox1.Text);

int b = Convert.ToInt32(TextBox2.Text);

int c = mys.Multiplication(a, b);

TextBox3.Text = c.ToString();

}

Step 11- After pressing the F5 function key to run the website, you will see:
