POWhere should I put the associated methods of a List<T> of datarows?

copied!<p>Preface: read <a href="https://stackoverflow.com/questions/1192894/how-to-store-tables-in-c-what-kind-of-data-structure-should-i-use">this</a> question. Let's say that I have all my stuff in a data structure described by <a href="https://stackoverflow.com/questions/1192894/how-to-store-tables-in-c-what-kind-of-data-structure-should-i-use/1192912#1192912">Skeet</a>. Now I want to write some methods dealing with this kind of data. This is what I have come up with: Ideally this kind of data should be in its own class. So I have decided to wrap the List of datapoints.</p> <pre><code>public class MeteoDataPoint { private readonly DateTime timeStamp; public DateTime TimeStamp { get { return timeStamp; } } private readonly double temperature; public double Temperature { get { return temperature; } } private readonly double airPressure; public double AirPressure { get { return airPressure; } } public MeteoDataPoint(DateTime timeStamp, double temperature, double airPressure) { this.timeStamp = timeStamp; this.temperature = temperature; this.airPressure = airPressure; } } public class MeteoDataPointList { private List<MeteoDataPoint> list; public MeteoDataPointList() { list = new List<MeteoDataPoint>(); } // expose some of List's functionality public void Add(MeteoDataPoint p) { list.Add(p); } public bool Remove(MeteoDataPoint p) { return list.Remove(p); } public void RemoveAt(int i) { list.RemoveAt(i); } public int Count { get { return list.Count; } } public MeteoDataPoint this [int i] { get { return list[i]; } } // and now I can wrtie my custom methods specific to my data public double AverageTemperature() { double sum=0; foreach (MeteoDataPoint m in list) { sum += m.Temperature; } return sum / list.Count; } } </code></pre> <p>What do you think? How can I improve on this? Is there a better way (maybe subclassing List or just a class with static methods for manipulating a List of MeteoDataPoint)? Should I care about a destructor?</p> <p><em>Note: Sorry if the question is too trivial, I have been doodling around with csharp, but this will be the first time I have to create something useful, and as the language provides so many ways to accomplish the same task I often find myself at crossroads wondering which way is the best.</em></p>

Querying!
