Setting a Generic Type to Zero

[Jonathan Wood]

I've decided to write a little routine using generics. That is, a method
that takes an out argument of any data type.

However, being the quirky language that C# is, I have the following problem.

The method returns a bool value that indicates if it is successful. If it is
successful, the out argument's value is set. But C# requires that I set the
value of this argument even if I'm not successful.

In the case of an integer, I would just set it to zero. But how can I do
similarly for all the other data types a generic method might be passed?

Thanks.

default(T). It's magic keyword that returns the default value for any
type. (0, 0.0, false or null).

Cool! I was wondering about some sort of special syntax. That's it.

Thanks!
