Checking for null before ToString()

Question

Here\'s the scenario...

if (entry.Properties[\"something\"].Value != null)
  attribs.something = entry.Properties[\"something\"].Value.ToString();
<         


        

Answer 1

As a variation to RexM's answer:

attribs.something = (entry.Properties["something"].Value ?? attribs.something).ToString()

The only downside would be that the attribs.something would be assigned a value (itself, in this example) even if entry.Properties["something"].Value was null - which could be expensive if the .something property did some other processing and/or this line executes a lot (like in a loop).
