Question

I have many objects (such as 10.000, more or less). Every object has3 values :

1. Index (decimal, such as 0,0 <= X <= 100.000,9);
2. A Latitude value;
3. A Longitude value;

and I need to perform some search due to the Index value. Which will be the light approch to this? List<MyObject>? I know there are hashtable, but only for 2 values…

I read these values from a .csv file and I’ll store it on application. WebForm, .NET 4.5.

Why don’t you use a Dictionary like this:

public class Position
{
    public Latitude  Latitude  { get ; set ; }
    public Longitude Longitude { get ; set ; }
}

public Dictionary<decimal,Position> Positions ;

Or use a Tuple in the dictionary:

public Dictionary<decimal,Tuple<Latitude,Longitude>> Positions ;
