Nullable types??
-
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.
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.

Nullable or Not. That is the question. Are they good or are they bad? What are YOUR thoughts?

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.

Yeah... And boy is that not slick. :rolleyes: ("Yay!" i thought to myself, upon hearing of this for the first time... "Now i can write generic code that treats value types and reference types the same!" The gods of .NET proceeded to laugh heartily at my naivete...)

Throw in something about dangling pointers.

Well, they're low in fat, sodium, and carbohydrates, and contain no alcohol; how can that be good? :confused:

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".

What about "raising" an exception?
