What is IIS? Why is it used?
It makes our computer to work as a Web server and provides the functionality to develop and deploy Web applications on the server.
IIS handles the request and response cycle on the Web server. It also offers the services of SMTP and FrontPage server extensions.

Default Access Modifier in C#
This is very basic thing we should come to know, so that i just recall this concept in this post.
An enum has default modifier as public
A class has default modifiers as Internal .
An interface has default modifier as public
A struct has default modifier as Internal
A methods, fields, and properties has default access modifier as "Private" if no modifier is specified.

Unable to cast object of type WhereSelectListIterator to type 'System.IConvertible'.
Unable to cast object of type WhereSelectListIterator to type 'System.IConvertible'.
When you find above error you can use single to avoid the error.
item.title = Convert.ToString(lstobj.Where(x => x.ID == item.id).Select(x => x.IdentifiersName).Single());
IDictionary in C#
Dictionary represent a collection of keys and values pair of data.
The Dictionary class is a generic class and can store any data types.
The Dictionary class constructor takes two parameters (generic type), first for the type of the key and second for the type of the value.
Dictionary Example program
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace iDictionary
{
class Program
{
static void Main(string[] args)
{
Dictionary<string, Int32> sampleDic = new Dictionary<string, int>();
sampleDic.Add("Babu", 1111);
sampleDic.Add("Prabhu", 2222);
sampleDic.Add("Harshad",2223);
Console.WriteLine("IDictionary Value");
Console.ReadKey();
foreach (KeyValuePair<string, Int32> item in sampleDic)
{
Console.WriteLine("Key = {0} ,Value = {1}", item.Key, item.Value);
}
Console.ReadKey();
Console.WriteLine("Thanks");
Console.ReadKey();
Console.WriteLine("----------------");
Console.WriteLine("Dictionary Prperties");
Console.WriteLine("Count: {0}", sampleDic.Count);
Console.WriteLine("----------------");
Console.WriteLine("Dictionary KeyCollection Prperties");
Dictionary<string, Int32>.KeyCollection keys = sampleDic.Keys;
foreach (string key in keys)
{
Console.WriteLine("Key : {0}", key);
}
Console.WriteLine("----------------");
Console.WriteLine("Dictionary ValueCollection properties ");
Dictionary<string, Int32>.ValueCollection val = sampleDic.Values;
foreach (Int32 item in val)
{
Console.WriteLine("Value : {0}", item);
}
Console.ReadKey();
}
}
