I can\'t seem to get a HashSet instance to work as expected. The code I used is as follows: import testing.Subclass;
I have a pretty big (100\'000s of entries) HashMap. Now, I need a HashSet containing all the keys from this HashMap. Unfortunately, HashMap only has a keySet() method which returns a开发者_StackOverfl
HashSet does not have an AddRange method, so I want to write an extension method for it. This is what I have:
How do I convert a HashSet<T> to 开发者_开发技巧an array in .NET?Use the HashSet<T>.CopyTo method.This method copies the items from the HashSet<T> to an array.
I\'m trying to create the extension method AddRange for HashSet so I can do something like this: var list = new List<Item>{ new I开发者_JS百科tem(), new Item(), new Item() };
I need a HashSet that preserves insertion ordering, are there any implementations of this in the开发者_JS百科 framework?Standard .NET HashSet do not preserve the insertion order.
