Using the ZIP operator

The ZIP operator used to parse the elements at the same index position in each squence. When one sequence is completes reading its elements, the result is returned.

Now, we add the Default.aspx page and write the following code:

  

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <center> 
    <div>
        <h1>Using the ZIP operator</h1>
        <asp:ListBox ID="lbDetail" runat="server" Height="480px" Width="500px"></asp:ListBox> <br /> <br />
        <asp:Button ID="btnDisplayRecord" runat="server" Text="Display Record" Font-Bold="true" OnClick="btnDisplayRecord_Click" />
    
    </div>
            </center>
    </form>
</body>
</html>

Now, double click on Display Record button and write the following code:-

  

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }


    protected void btnDisplayRecord_Click(object sender, EventArgs e)
    {
        lbDetail.Items.Clear();

        string[] Name = { "Santosh kumar singh", "Manorma arya", "Prem Kumar", "Pooja", "Narendra Modi", };
        string[] Position = { "Dotnet Programmer", "Manger", "PSA", "Developer", "PM", };
        int[] Year = { 4, 3, 25, 2, 6 };

        var q = Name.Zip(Position, (a, b) => a + " is the " + b + " of the company");

        var r = q.Zip(Year, (c, d) => c + " with " + d + " years of experience");

        foreach (var data in r)
        {
            lbDetail.Items.Add(data);
        }    
    }
}

Now run the application and click on Display Record button and get output.
