Casting Ado.net DataReader to IDataRecord giving strange result

Question

I have a query that I run against the database, and I can see that there is a record for 31/05/2013. When I run this query from C# with ADO.NET, and then use the following

Answer 1

I think that you are missing record in first example because you move reader by one and then cast it.

Try this change and see if it worked:

var timeSeries = new List();  
using (var reader = cmd.ExecuteReader())
{
    if (reader.HasRows)
    {
        timeSeries = reader.Cast()
            .Select(r => new TimeSeries
                 {
                     MidRate = (double)r["MidRate"],
                     RiskFactorName = (string)r["RiskFactorName"],
                     SeriesDate = (DateTime)r["SeriesDate"]
                 }).ToList();
    }
}
