bool areNullablesGood = ("the month".indexOf('R') >= 0); Well, that answers that.

but he did not specify whether having the R is good or not ;P

They are good when you need a nullable type. Or, when you need compatibility with other platforms (while designing web services contracts, for example).

Neither. You use the correct tool for the job. Nullable types are just another tool in the toolbox. They serve a specific surpose. I don't qualify them as "good" or "bad".

Sounds like a medical condition that afflicts older developers. [cue drug company commercial here] Do you suffer from Stack Overflow? Is this affecting your love life? Work? Family? Friends? Millions of aging Software Developers, like you, live with SOF everyday. Well, worry no more. With Stacagra, you'll regain your confidence and management over your Stack once again. :rolleyes:

But no longer in 2009...True. What ever is best for the job. Simple. easy. For some reason when I code, I sit for hours wasting time, trying to find the best way foward. I know there are always a handfull of ways to accomplish a given task. I'm just trying to find the "best",most effecient,simplest solution. Maybe that it. Time. Every ms counts. Oh well. Think it's just monday driving me up the wall. Thanks anyway.

That seems pretty close to the truth, as (1) months have at most one capital letter (never an R), (2) and "the month" has none. :)

The quality and detail of your question reflects on the effectiveness of the help you are likely to get. Show formatted code inside PRE tags, and give clear symptoms when describing a problem.

Don't use them when you don't have to. Every time you call an API expecting a non nullable value you'll have to do validation/conversion of your nullables.

Useless, because there's no mapping of a nullable type to an object with value DBNull.Value. Marc

Given that the inventor of null calls it his "billion dollar mistake[^]", I think it's safe to say null references are bad. Or did you mean

I usually use them in conjunction with a database and linq. But I don't see why they can't be used whenever the need arises. http://qconlondon.com/london-2009/presentation/Null+References:+The+Billion+Dollar+Mistake[^]

Well, all value types are non-nullable by default. You can make them nullable by wrapping them in a class. This is done automatically in .NET with the "?" operator.
