ToDateTime can't be overriden but you can use TryParse:

bool valid = DateTime.TryParse("date string", out d);

No, you can't override static methods. But you can write your own static method:

// TODO: Think of a better class name - this one sucks :)
public static class MoreConvert
{
    public static DateTime? ToDateTimeOrNull(string text)
    {
        return text == null ? (DateTime?) null : Convert.ToDateTime(text);
    }
}

Note that the return type has to be DateTime? because DateTime itself is a non-nullable value type.

You might also want to consider using DateTime.ParseExact instead of Convert.ToDateTime - I've never been terribly fond of its lenient, current-culture-specific behaviour. It depends where the data is coming from though. Do you know the format? Is it going to be in the user's culture, or the invariant culture? (Basically, is it user-entered text, or some machine-generated format?)

You can use DateTime.Parse instead, if you are sure that your string is in correct format.
