LINQ to String Array

LINQ to String Array means writing the LINQ queries on string array to get the required data. If we use LINQ queries on string arrays, we can get the required elements easily without writing the much code.

Syntax of LINQ to String Array

Here is the syntax of writing the LINQ queries on string Arrays to get the required element from array collection.

IEnumerable<string> result = from a in arr

                                         select a;

In the above syntax, we have written the LINQ query to get the data from the "arr" string array.

Example of LINQ to String Array

Here is the example of LINQ to String Array to get the elements from the string array sequence where the name starts with "S".

using System;
using System. Collections;
using System.Collections.Generic;
using System. Linq;
using System. Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Programme2
    {
        static void Main(string[] args)
        {
//create an array of type string
            string[] array = { "Vaishali", "Shalu", "Akshay", "Akki" };
/*IEnumerable will iterate over the collection of data use 
Linq query to select the particular element which starts from s*/
            IEnumerable<string> result = from a in array
            where a.ToLowerInvariant().StartsWith("s")
            select a;
    //foreach loop is used to print the output which is in the result
            foreach (string item in result)
            {
                Console.WriteLine(item);
            }
                Console.ReadLine();
         }
    }
}
