How to get nullable DateTime out of the database

Question

My SQL Server database contains nullable DateTime values. How can I convert them to a nullable DateTime object in my application in C#?

This is what I would think it

You need to check if the value "is DBNull" rather than just null. I posted a small helper class on my blog: http://improve.dk/archive/2007/10/08/handling-dbnulls.aspx

Once you implement the class, you use it like this:

DateTime? dt = DBConvert.To<datetime?>(sqldatareader[0]);
