To implement this concept you need to follow the below steps :
Step1 :
Create a new Asp.net website in Visual Studio and write the following html
code in the design part of the Default.aspx page.
Design Page :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<table class="style1">
<tr>
<td class="style2">
First Number :</td>
<td>
<asp:TextBox ID="txtnum1"
runat="server"></asp:TextBox>
</td>
</tr><tr>
<td class="style2">
Second Number :</td>
<td>
<asp:TextBox ID="txtnum2"
runat="server"></asp:TextBox>
</td>
</tr><tr>
<td class="style2">
</td>
<td>
<asp:Button ID="btnAdd" runat="server"
onclick="btnAdd_Click"
Text="Add"
Width="66px"
/>
</td>
</tr><tr>
<td class="style2">
Result :</td>
<td>
<asp:Label ID="lblResult"
runat="server"
Text=""></asp:Label>
</td></tr>
</table>
</form>
</body>
</html>
Step2:
Now open the Default.aspx.cs page and write the following source code.
Default.aspx.cs code :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default :
System.Web.UI.Page
{
protected void
Page_Load(object sender, EventArgs e)
{
}
protected void
btnAdd_Click(object sender, EventArgs e)
{
WebService ws = new
WebService();
lblResult.Text = ws.add(Convert.ToInt32(txtnum1.Text),
Convert.ToInt32(txtnum2.Text)).ToString();
}
}
Step3:
Now build the Solution and Debug it for the output.
