This answer posted by me soft.narayan@gmail.com,If u have
any query please let me know......

Using an object like an array is called Indexer.
Indexer is similar to properties.Indexer is a collection of
set and get procedures.Indexer name must be "this" only.
One class can have only one indexer.

Syntax to create Indexer:
string s
public string firstname
{
set{ s=value;}
get (return s;}
}

string[] x=new string[5];
public string this[inti]
{
set {x[i]=value}
get { return x[i]}
}
}

Answer / priya

1. An index is identified by it's signature. But a property
is identified it's name.
2. An indexer is always an instance member, but a property
can be static also.
3. An indexer is accessed through an element access. But a
property is through a member access.

Answer / uday

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();

}
}
