Practical 13AIM: Create a web service to add two numbers.
Design:
WebService.asmx:<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" Class="WebService" %>
WebService.asmx.cs:using System;using System.Web;using System.Web.Services;
/// <summary>/// Summary description for WebService/// </summary>[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 WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components //InitializeComponent();
}
[WebMethod] public string HelloWorld() { return "Hello World"; }
[WebMethod] public int add(int a, int b) { return a + b; }
[WebMethod] public int sub(int a, int b) { return a - b; }
[WebMethod] public int mul(int a, int b) { return a * b; }
[WebMethod] public int div(int a, int b) { return a / b; }
}
Output:
