How do I use collections in C#?
In C#, collections are used to store groups of related objects. Common types include arrays, lists, dictionaries, and sets.
Can you explain the difference between a List and an Array?
Sure! An Array has a fixed size and can store elements of the same type, while a List is dynamic and can grow or shrink as needed.
What about dictionaries? When should I use them?
Dictionaries are key-value pairs, ideal for fast lookups. Use them when you need to associate unique keys with specific values.
Can you give me an example of using a List in C#?
Certainly! Here's a simple example: List<int> numbers = new List<int>(); numbers.Add(1); numbers.Add(2);
This creates a list of integers.
