Can I override Convert.ToDateTime ()?

Can I override Convert.ToDateTime()? I do not want to check 100 times or more whether the string is zero, and if not, convert it to DateTime. Can I override this function to check if it is null and then return null, otherwise it will convert it.

No, you cannot 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 must be DateTime?, because it is DateTimeitself a value type that is not null.

DateTime.ParseExact Convert.ToDateTime - , - . , . ? ? ( , - ?)

ToDateTime , TryParse:

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

Instead, you can use DateTime.Parseit if you are sure that your string is in the correct format.
