This is pretty simple. In fact, I am writing this because most example show you this :
public object this[int index]
{
get { return collection[index]; }
set { collection[index] = value; }
}
In fact, you should return the type of your collection. So, if your object contains a collection of Person than you should write :
public Person this[int index]
{
get { return collection[index]; }
set { collection[index] = value; }
}
This way, the value returned doesn’t require to be casted.
