Hi OriginalGriff Yess This is right Boss :)

“==” compares if the object references are same while “.Equals()” compares if the contents are same. So if you run the below code both “==” and “.Equals()” returns true because content as well as references are same. Take 2 variables & test it ,you came to clear conclusion....

The idea of homework is that you think about it and form your own conclusions! So why not explain what you think, justify it and we'll see if we agree? But us just writing it all out for you doesn't help anyone - least of all you. :laugh: Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Hi Bill, it's a C# 6.0 feature, readonly auto-properties. Like readonly fields, they can be initialized where they're declared or in the constructor. Here's a nice write-up from Jon Skeet: C# 6 in action[^] Thank you guys for this interesting thread :) cheers, Sascha

GoF had a pretty list, website and a book, but they do not own the term. David A. Gray wrote: When the Gang of Four gave them a new name to sell their book We already had a null object and a memento in our codebase. Java-land was defining patterns every day. A design-pattern is merely an OO-algorithm. At least, that is how it was explained to me at that time. My memento interface looks as if it is simply binary data that wants to be streamed to disk.
