Can someone explain what the code does step by step?

I don't understand, what does the .replace do and (" ", string.Empty)? And what seems to be the purpose of it?

It essentially just does a search-and-replace on the string it's called on. The first argument is the string to search for, the second argument is the string to replace matches with. This code just replaces all spaces in the string with an empty string, i.e. just removing all spaces.

oh ok thanks, how do i call on the second method and is there a specific meaning to "orig"? public CompactString(CompactString orig) { this.saveString = orig.saveString; }

orig is just the parameter name That method is a constructor It's called by new
