C# Hashsets - Understand them, use them, LOVE them
So, what is C#?
C# (pronounced "See Sharp") is a modern, object-oriented, and type-safe programming language. C# enables developers to build many types of secure and robust applications that run in .NET. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers. This tour provides an overview of the major components of the language in C# 8 and earlier. If you want to explore the language through interactive examples, try the introduction to C# tutorials.
And what are Hashsets?
In C#, HashSet is an unordered collection of unique elements. This collection is introduced in .NET 3.5. It supports the implementation of sets and uses the hash table for storage. This collection is of the generic type collection and it is defined under System.Collections.Generic namespace. It is generally used when we want to prevent duplicate elements from being placed in the collection. The performance of the HashSet is much better in comparison to the list.

Under the arrays your adding stuff into the list not the array
I've worked with several languages including Java, C++, and Python. In my opinion C# (now dotnet core) has been the most comprehensive and clear syntax I've experienced with a lot of great new features with every new version. Just love it.
Hi there, someone probably mentioned this but your array section is adding to your list
dude introduced hashsets to us like it's our lord and saviour. Now I am a disciple.
Thank you Brother 😇 your videos help me to learn about .Net c#.
Happy to hear that. I'm also excited to learn more and teach what I've learned :)
Very well presented. Thank you.
Great video. According to you, what are the most used methods for HashSets?
Just curious, is this quicker than LINQ using Distinct() ?
thanks!
Great video. I find myself using collections more than hashsets in c#, because normally the data has key-value pairs (such as id and description). And in MVC drop downs for example normally require a key value pair like a selectlist. Do you have any thoughts on collections vs lists vs hashsets? After watching this I’m wondering if there are places I can simplify collections into hashsets, or do you find most real-life apps require collections because we normally have unique ids associated with our data?
Hi, I think that this is quite hard to answer because it relies on the purpose of your code. Fact is, that you should try to take the best data structure for your codes purpose. Usually you will be fine with any kind of collection and if you do not care about duplicates an array or a list will be your best bet. If you need kvps then a dictionary and if they you don't want duplicates, you pick the hashset.
It really depends... :)
