What is your experience with using LINQ in development practice?

LINQ (Language Integrated Query) is a powerful tool in C# for working with data collections, allowing you to write SQL-style queries directly in code.

In development practice, I have used LINQ for:

• Filtering data from lists and arrays:

  var adults = people.Where(p => p.Age >= 18).ToList();
  

• Data projection (select):

  var names = people.Select(p => p.Name).ToList();
  

• Sorting:

  var sorted = people.OrderBy(p => p.LastName).ThenBy(p => p.FirstName);
  

• Grouping:

  var grouped = people.GroupBy(p => p.City);
  

• Collection joins:

  var query = from order in orders
              join customer in customers on order.CustomerId equals customer.Id
              select new { order.Id, customer.Name };
  

LINQ significantly simplifies working with data, making the code more readable and declarative.
