How Can LINQ Simplify Finding Items in C# Lists?

Finding Items in Lists with LINQ

In C#, developers commonly leverage loops or anonymous delegates to locate items within lists. However, LINQ offers alternative methods for this task.

Using LINQ to Find Items

LINQ (Language Integrated Query) provides several approaches to find items in lists:

1. Single

var result = myList.Single(s => s == search);

Single returns a solitary result but raises an exception if multiple or no results are found.

2. Where

var results = myList.Where(s => s == search);

Where yields an IEnumerable containing all matches, including the possibility of zero or multiple results.

3. First

var result = myList.First(s => s == search);

First retrieves the initial item that satisfies the specified predicate, and throws an exception if no match is found.

4. FirstOrDefault

аналогично First, но при отсутствии совпадений возвращает null (ссылочный тип) или значение по умолчанию (тип значения).
