using System;

namespace oops

public class A
{
public A()
{
Console.WriteLine("A");
Console.WriteLine("===============================");
}

{
Console.WriteLine("Add");
}

public class B : A

public B()
{
Console.WriteLine("B");
Console.WriteLine("===============================");

public void Sub()

Console.WriteLine("Sub");
}

}

class Program

static void Main(string[] args)
{
A objA = new A();

B objB = objA as B;
A objAB = new B();

B objBB = objAB as B;
objBB.Sub();

if (objB is B)
{
objB.Add();
}
else
{
Console.WriteLine("objB is not B");
}

//objA.Add();
Console.ReadLine();
}
}
}

Out put of the code is

A

===============================

A

===============================

B

===============================

Sub

objB is not B

git remote show origin

Create a local branch that tracks one of the remote branches and then use that local branch:

git checkout –track -b name_of_local_branch origin/name_of_remote_branch

If you have not done a pull since someone else created the remote branch, you may first need to do:

git fetch

Remove branch from repo.

git push {repo} :heads/{branch}

Ex:

git push origin :somebranch

removes somebranch

I am reading more on design patterns from this  article after little theory session here is working code. Key point was all of the collection classes in the System.Collections namespace, as well as arrays, implement IEnumerable and can therefore be iterated over.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class IteratorPattern
{

static void Main(string[] args)
{

int[] values = new int[] { 1, 2, 3, 4, 5 };
IEnumerator<int> e = ((IEnumerable<int>)values).GetEnumerator();
while (e.MoveNext())
{
Console.Write(e.Current.ToString() + " ");
}

Console.ReadKey();
}
}

}

Well I am investigating design patterns by reading an article so after reading a bit I thought it would be nice if I write some code and test it.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
/// <summary>
/// Product Class
/// </summary>
public class Product
{
public delegate void NameChangeEventHandler(int a);
public event NameChangeEventHandler NameChanged;
private string _name;
public string Name
{
get
{
return _name;
}
set
{
_name = value;
if (NameChanged != null)
{
NameChanged(5);
}
}
}

public Product(string name)
{
Name = name;
}
public void PrintName()
{
Console.WriteLine("ProductName={0}", Name);
}
}

/// <summary>
/// Test Class
/// </summary>
public class Test
{
public Test(Product P)
{
P.NameChanged += new Product.NameChangeEventHandler(ChangeDetected);
}
public void ChangeDetected(int a)
{
Console.WriteLine("change found,argument passed is {0}",a);
}

}

static void Main(string[] args)
{
Product p = new Product("najam awan");
p.PrintName();
Test t = new Test(p);
p.Name = "najaf awan";
p.PrintName();
Console.ReadKey();

}
}
}

Below code is using Product class with event and delegate for event handling and other class named Test is using this class and manipulate product class data. If you change the Name of the product event will fire.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
/// <summary>
/// Product Class
/// </summary>
public class Product
{
public delegate void NameChangeEventHandler(int a);
public event NameChangeEventHandler NameChanged;
private string _name;
public string Name
{
get
{
return _name;
}
set
{
_name = value;
if (NameChanged != null)
{
NameChanged(5);
}
}
}

public Product(string name)
{
Name = name;
}
public void PrintName()
{
Console.WriteLine("ProductName={0}", Name);
}
}

/// <summary>
/// Test Class
/// </summary>
public class Test
{

public void ChangeDetected(int a)
{
Console.WriteLine("change found,argument passed is {0}",a);
}
public void TestProduct()
{
Product p = new Product("najam awan");
p.PrintName();
p.NameChanged += ChangeDetected;
p.Name = "najaf";
p.PrintName();
Console.ReadKey();
}

}

static void Main(string[] args)
{
Test t = new Test();
t.TestProduct();
}
}
}
