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.

Taking the code from Vark111's post, and assuming C#:
if (null == value || (null).Equals(value)) {
If value isn't null, the second part will be evaluated. Since the second part tries to call the Equals method on a null reference, it would throw a NullReferenceException. D'Oh! | :doh:

Thankfully, the C# compiler is smart enough to prevent you from compiling this code - you'll get an "Operator '.' cannot be applied to operand of type '<null>'" compiler error.
