Program Code – Mastering Language Integrated Query for Efficient Data Manipulation
using System;
using System.Collections.Generic;
using System.Linq;
namespace LINQMasterclass
{
class Program
{
static void Main(string[] args)
{
// Initializing a list of names
List<string> names = new List<string>()
{
'John', 'Jane', 'Sarah', 'Arjun', 'Mohammed', 'Ying', 'Pedro', 'Maria'
};
// Using LINQ to filter names longer than 4 characters
var filteredNames = from name in names
where name.Length > 4

Console.WriteLine(name);
}
// Initializing a list of numbers
List<int> numbers = new List<int>() { 2, 3, 5, 7, 11, 13, 17, 19 };
// Using LINQ to find the sum of even numbers
var sumOfEvenNumbers = numbers.Where(n => n % 2 == 0).Sum();

Code Explanation:
The provided code showcases the power of Language Integrated Query (LINQ) in manipulating and querying data collections efficiently in a C# program.
- Filtering: It begins with filtering names longer than 4 characters from a list using a LINQ query. This demonstrates how LINQ can be utilized to easily filter data based on customized conditions. The
whereclause is pivotal here, narrowing down the elements to those meeting the specified criteria. - Aggregation: Next, the code calculates the sum of even numbers from a list. This segment illustrates LINQ’s ability to perform complex aggregations with minimal code. The
Wheremethod filters even numbers, and theSummethod aggregates them, showcasing the fluency and intuitiveness of LINQ for common data tasks. - Grouping: Finally, the code groups names by their first letter. This is achieved through the
group byclause in LINQ, which organizes elements into categories. The resulting grouped data is then displayed, providing a clear example of how LINQ can transform and categorize data efficiently for better organization and readability.
Overall, this code exemplifies the core strengths of LINQ: its expressiveness, ability to significantly reduce the amount of code for complex data operations, and its seamless integration with C# language, making data querying and manipulation tasks more intuitive and efficient for developers.
