Introduction about Dictionary

If you know about array , array can store only single value or single type value  in the memory . It can't store double value in single memory location with different types. Suppose you want to store name and age of the person in single memory location then you must use collection . Here in this example we will use Dictionary collection.
The simple syntax of dictionary object are

Dictionary<type, type> dict =  new Dictionary<type, type>(); 
The above mention syntax is says to you that if you want to store person age with person name then you must use Dictionary
for example 

//create instance of the the Dictionary 
Dictionary<string,int> dict =new Dictionary<string,int>();

//Add item to the dictionary
dict.Add("my name is jacob", 26);
dict.Add("my name is lefore",27);

Now if you want to show of the data , You can use any data control such as GridView , FormView , ListView etc.

Lets take an simple example to bind GridView using Dictionary collection
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default11.aspx.cs" Inherits="Default11" %>

<!DOCTYPE html>

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None">
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <EditRowStyle BackColor="#999999" />
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#E9E7E2" />
            <SortedAscendingHeaderStyle BackColor="#506C8C" />
            <SortedDescendingCellStyle BackColor="#FFFDF8" />
            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default11 : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
        Dictionary<string, int> dict = new Dictionary<string, int>();
        dict.Add("My name is jacob", 26);
        dict.Add("My name is lefore", 27);
        dict.Add("My name is michel", 24);
        dict.Add("My name is lisa", 19);
        GridView1.DataSource = dict;
