The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrasing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

Not quite. IIf is a function[^], and as such it evaluates both arguments before checking the condition. So while this works in C#:
someObject == null ? "Null" : someObject.ToString()
the equivalent using IIf will throw a NullReferenceException:
IIf(someObject Is Nothing, "Null", someObject.ToString()) ' Boom!
The real ternary operator for VB.NET is the If operator[^], which was added in .NET 3.5:
If(someObject Is Nothing, "Null", someObject.ToString()) ' No Boom.
