Question

These both seem to do the same thing.. I’m wondering which one I should use, you would prefer to read, is more efficient, their differences, et cetera..

Lambda #1

synchronizationContext.Post(m => log.AppendText(message), null);

Lambda #2

synchronizationContext.Post(m => log.AppendText(m), message);

My only concern is that with the second one, even though it may look more read-able, isn’t their boxing and unboxing because of the Post method takes an object and message is a string?

Thanks.

Answer 1

Strings are stored in the managed heap, so they don’t need to be boxed/unboxed.

Because you don’t have do any extra casting (from object to string), I would go with this one:

synchronizationContext.Post(m => log.AppendText(message), null);
