Question

I’ve found this piece of code on Koders:

private ServiceProvider SiteServiceProvider {     get     {         if (serviceProvider == null)         {             serviceProvider = new ServiceProvider(site as VSOLE.IServiceProvider);             Debug.Assert(serviceProvider != null, 'Unable to get ServiceProvider from site object.');         }         return serviceProvider;     } } 

I’m wondering, is there any possible way the Debug.Assert(serviceProvider != null could trigger? I’m under the impression that new could only be aborted by an exception, in which case the assert would never be reached.

Answer 1

It’s possible that the ServiceProvider overrides the !=/== operator, so that for an invalid state the comparison to null returns true.

Looks strange anyway.
