Answer 1

DateTime.ParseExact Method (String, String, IFormatProvider)

DateTime dt = DateTime.ParseExact(dateString,formatString);
dt = (dt.Month == DateTime.Now.Month) ? DateTime.Now : dt;

If your calling this alot in a loop performance may be better if you only call DateTime.Now once and store it in a variable before comparison, since DateTime.Now is a fairly expensive operation.

If the SQL server column is of type DateTime then you don't need to worry about the format, jut pass the DateTime object and it will work.
