LINQ to Strings

LINQ to strings is nothing but writing the LINQ queries on String to get the required data from the string sequence. In LINQ, we can write queries on strings along with traditional string functions and regular expressions to perform the required operations on strings using the LINQ.

Syntax of LINQ to Strings

The syntax of writing the LINQ queries is:

In the above syntax, we have written the LINQ query on String to get the distinct element.

Example of LINQ to Strings

Here is the example of writing the LINQ queries on String to split the String into words in C#.

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 a string 'str1' 
            string str1 = "Welcome     to   Java T Point.Com";
//here StringSplitOptions.RemoveEmptyEntries() is used to remove the spaces between the words.
            var result = from s in str1.ToLowerInvariant().Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)
            select s;
            foreach (var item in result)
            {
                Console.WriteLine(item);
            }
                Console.ReadLine();
        }
    }
}

In the above example, we have written the simple query in LINQ to split the string "str" into multiple words. Here "str" string object contains many spaces between words, and to remove these spaces, we use "StringSplitOptions.RemoveEmptyEntries" properties. In case if we use traditional coding, we need to write a lot of code to split the String and remove the spaces between words.
