You could define a custom class which will represent your data:

public class Item
{
    public int Power { get; set; }
    public DateTime Date { get; set; }
}

and then you could use a LINQ query on your DataSet to extract the necessary information:

DataSet dataSet = ...
Item[] result = dataSet
    .Tables[0]
    .Rows
    .Cast<DataRow>()
    .Select(row => new Item
    {
        Power = row.Field<int>("power"),
        Date = row.Field<DateTime>("date"),
    })
    .ToArray();
