How to implement data container with instance["variable_name"] access?

Question

I am using DataTable["content_name"], DataReader["content_name"], but I do not know, how to create my own object using this way to access data.

I want to create datareader result container (DataTable makes me some unwanted queries to db on firebird).

Answer 1

Something like

public class MyClass
{
  private List<String> _myData;

  public MyClass()
  {
    _myData = new List<String>();
  }

  public String this[String argIndex]
  {
    get
    {
      return _myData[argIndex];
    }
    set
    {
      _myData[argIndex] = value;
    }
  }
}

It's the this bit that usually stumps you until you know it, bit unobvious...
