I stumbled across this code and am too proud to go and ask the author what it means.
Hashtable^ tempHash = gcnew Hashtable(iterators_);
IDictionaryEnumerator^ enumerator = tempHash->GetEnumerator();
What is gcnew and how important is it to use that instead of simply new? (I'm also stumped by the caret; I asked about that over here.)
gcnew is for .NET reference objects; objects created with gcnew are automatically garbage-collected; it is important to use gcnew with CLR types
gcnew is an operator, just like the new operator, except you don't need to delete anything created with it; it's garbage collected. You use gcnew for creating .Net managed types, and new for creating unmanaged types.
