Print Recordset Details from IDataReader

Occasionally when working with recordsets returned by a stored procedure in an IDataReader, it can be helpful to print information about the columns returned. I like to do this when making a DTO class that mirrors a recordset to ensure that my class’s properties are typed consistently with the recordset. Printing the column details can be accomplished easily with the following code:

IDataReader reader = GetDataReader();
for (int i = 0; i < reader.FieldCount; i++)
{
    Console.WriteLine("Name:{0}, Type:{1}",
        reader.GetName(i),
        reader.GetDataTypeName(i));
}
