Properties are not like variables, rather they are calling
methods. They dont be allocated memory like variables.
They(get,set accessors) will be called automatically when
we assigne value or refer the value.
class ProperyCls
{
string name;
public string Name
{
get
{
return name;
}
set
{
Console.WriteLine("In Set method the value
is "+value);
name = value;
}
}
}
class Program
{
static void Main(string[] args)
{
ProperyCls pObj = new ProperyCls();
//Here the set method will be automatically
called
pObj.Name = "Hello";
//Here the get method will be called
automatically
Console.WriteLine("In get method the value is "
+ pObj.Name);
Console.ReadKey();
}
}
Indexers are different in the context when i create
multiple instances of the class and assign properties for
each of the instances. Indexers can be defined with "this"
keyword.
class ProperyCls
{
public int this[int i]
{
get
{
return 20;
}
set
{
Console.WriteLine("In set the value is " +
value + "at index" + i);
}
}
}
class Program
{
static void Main(string[] args)
{
ProperyCls pObj = new ProperyCls();
pObj[1] = 10;
pObj[2] = 30;
Console.WriteLine("In get method the value
returned is " + pObj[1]);
Console.ReadKey();
}
}
