                    USING LINQ IN C#

LINQ (Language Integrated Query) is a set of language features that provides a unified syntax for querying data from various sources. It allows you to write queries in a syntax that is similar to SQL, but is integrated into the C# or VB.NET language.

Here are a few examples of LINQ queries in C#:

1. Querying a list of integers to find all numbers that are greater than 5:

List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

var result = from n in numbers
             where n > 5
             select n;

2. Querying a list of strings to find all strings that start with the letter "A":

List<string> words = new List<string> { "apple", "banana", "cherry", "date", "elderberry" }; 
var result = from w in words
             where w.StartsWith("A")
             select w;

3. Querying an array of objects to find all objects that have a certain property value:

class Person 
{ 
public string FirstName { get; set; } 
public string LastName { get; set; } 
public int Age { get; set; } 
} 
 Person[] people = {
    new Person { FirstName = "John", LastName = "Doe", Age = 30 },
    new Person { FirstName = "Jane", LastName = "Doe", Age = 28 },
    new Person { FirstName = "Bob", LastName = "Smith", Age = 35 },
    new Person { FirstName = "Alice", LastName = "Smith", Age = 32 }
}; 
var result = from p in people
             where p.LastName == "Smith"
             select p;
