What are the different collection types in C# and how do I use them?
In C#, there are several collection types, including Arrays, Lists, Dictionaries, and HashSets. Each serves different purposes.
Can you explain when to use a List versus an Array?
Use an Array when you know the size in advance and need fast access. Use a List for dynamic sizing and more flexibility.
What about Dictionaries? When should I use them?
Dictionaries are great for key-value pairs. Use them when you need to quickly look up values based on unique keys.
Are there any performance considerations I should be aware of?
Yes, performance can vary. Arrays are fastest for fixed-size data, while Lists and Dictionaries offer more flexibility but may have overhead.
