==An Anonymous Type Assigned to a Variable Declared with the var Keyword==

<source lang="csharp">using System;
public class MainClass {
public static void Main() {
var unnamedTypeVar = new { firstArg = 1, secondArg = "Joe" };
Console.WriteLine(unnamedTypeVar.firstArg + ". " + unnamedTypeVar.secondArg);
}
}</source>

==An Example of Collection Initialization==

<source lang="csharp">using System.Collections.Generic;
using System;
public class MainClass {
public static void Main() {
List<string> presidents = new List<string> { "AAAA", "BBBBBB", "CCCCCCCC" };
foreach (string president in presidents) {
Console.WriteLine(president);
}
}
}</source>

==Explicit Range Variable==

<source lang="csharp">using System;
using System.Collections;
using System.Linq;
using System.ruponentModel;
class MainClass
{
static void Main()
{
ArrayList list = new ArrayList { "First", "Second", "Third" };
var strings = from string entry in list
select entry.Substring(0, 3);

foreach (string start in strings)
{
Console.WriteLine(start);
}
}
}</source>

==Instantiating and Initializing an Anonymous Type Using Object Initialization==

<source lang="csharp">using System;
public class MainClass {
public static void Main() {
var address = new {
address = "First Street",
city = "Vancouver",
state = "GA",
postalCode = "99999"
};
Console.WriteLine("address = {0} : city = {1} : state = {2} : zip = {3}",
address.address, address.city, address.state, address.postalCode);
Console.WriteLine("{0}", address.GetType().ToString());
}
}</source>

==Reflecting result from Linq==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Linq;
using System.Linq;
class Program
{
static void Main(string[] args)
{
string[] currentVideoGames = {"q", "2",
"this is a test", "aaa",
"eee", "System"};
var subset = from game in currentVideoGames
where game.Length > 6
orderby game
select game;
foreach (var s in subset)
Console.WriteLine("Item: {0}", s);
Console.WriteLine("resultSet is of type: {0}", subset.GetType().Name);
Console.WriteLine("resultSet location: {0}", subset.GetType().Assembly);

}
}</source>

==Using var==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Diagnostics;
class MyPC {
public Int32 Id { get; set; }
public Int64 Memory { get; set; }
public String Name { get; set; }
}
class LanguageFeatures {
static void Main(string[] args) {
var processes = new List<MyPC>();
foreach (var process in Process.GetProcesses()) {
var data = new MyPC();
data.Id = process.Id;
data.Name = process.ProcessName;
data.Memory = process.WorkingSet64;
processes.Add(data);
}
Console.Write(processes);
}
}</source>
