Polymorphism

namespace ConsoleApplication2
{
class A
{
public virtual void Amethod( )
{
Console.Write( "A method" );
}
}

class Program : A
{
public override void Amethod( )
{
Console.WriteLine( "B method" );
}
public void Bmethod()
{
Console.WriteLine("C method");
}

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

//Program objA = new Program( );
objA.Amethod( );

}
}


}

Singleton Sample

Singleton - Construction should be private. Should allow to create instance using members method(CreateInstance):

namespace ConsoleApplication1
{

class Singleton
{
public static Singleton obj = null;
private Singleton( )
{
}

public static Singleton CreateInstance()
{
if ( obj == null )
obj = new Singleton( );

return obj;
}
}

class Class1
{
static void Main( string[ ] args )
{
Singleton obj1 = Singleton.CreateInstance( );

Singleton obj2 = Singleton.CreateInstance( );
if ( obj1 == obj2 )
Console.Write( "Objects are same" );
}
}
}

Dotnet Authentication, Authorization - Sample

Web.config
<authentication mode="Forms" >
<forms name="login" loginUrl="login.aspx" defaultUrl="Default.aspx" >
<credentials passwordFormat="Clear" >
<user name="ram" password="ram" />
</credentials>
</forms>
</authentication >

Login.aspx.cs

if (FormsAuthentication.Authenticate("ram", "ram"))
FormsAuthentication.RedirectFromLoginPage("ram", true);
else
Response.Write("Not valid user");
Web.config
<authorization>
<allow roles="Admin" />
<deny roles="Sales" />
</authorization>

Default.aspx.cs

if (User.IsInRole("Admin"))
Response.Write ("You are an Administrator");
HttpContext.Current.User.Identity.IsAuthenticated
