What's the equivalent of `Nothing`?

Published 12 March 04 02:26 AM

For reference types, the equivalent of VB's Nothing is C#'s null. For value types, it's the default value - 0, false, etc.

why

if (notvaluetype) // can't check for null, instead complains not being bool ? i find this very annoying
# Jon Skeet said on March 15, 2004 1:32 AM:: It's *great* not to allow "if" to work on anything other than bool, in my view. It means there's no point in writing comparisons the "wrong" way round as you sometimes see in C/C++:

if (5==x)

The above is to avoid the typo of:

if (x=5)

- but in C# the latter doesn't compile anyway.
