How can I search for an item in a C# collection?

How can I search for an item in a C# collection?

You can use methods like Contains, Find, or LINQ queries to search for items in collections like lists or arrays.

Can you show me an example using a List?

Sure! Here's a simple example:

List<string> fruits = new List<string> { "apple", "banana", "cherry" };
bool hasBanana = fruits.Contains("banana");

What if I want to find an object in a list of custom objects?

You can use the Find method with a predicate. For example:

List<Person> people = new List<Person>();
Person found = people.Find(p => p.Name == "John");

Are there performance considerations I should be aware of?

Yes, the performance can vary based on the collection type. For example, searching in a List is O(n), while a HashSet is O(1) on average.
