Write a program in C# Sharp to find a string that starts and ends with a specific character.

Sample Solution:

C# Sharp Code:

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

class LinqExercise8  
{  
    static void Main(string[] args)  
    {  
        string chst, chen; // Declaring variables to store starting and ending characters
        char ch; // Declaring a variable to temporarily store a character input

        string[] cities =  // Array containing city names
        {  
            "ROME", "LONDON", "NAIROBI", "CALIFORNIA", "ZURICH", "NEW DELHI", "AMSTERDAM", "ABU DHABI", "PARIS"  
        };  

        Console.Write("\nLINQ : Find the string which starts and ends with a specific character : "); 
        Console.Write("\n-----------------------------------------------------------------------\n");	
        Console.Write("\nThe cities are : 'ROME','LONDON','NAIROBI','CALIFORNIA','ZURICH','NEW DELHI','AMSTERDAM','ABU DHABI','PARIS' \n");	

        Console.Write("\nInput starting character for the string : "); 
        ch = (char)Console.Read(); // Accepting input for starting character
        chst = ch.ToString(); // Converting the character input to a string
        Console.Write("\nInput ending character for the string : "); 
        ch = (char)Console.Read(); // Accepting input for ending character
        chen = ch.ToString(); // Converting the character input to a string

        var _result = from x in cities  // LINQ query to filter cities based on starting and ending characters
                      where x.StartsWith(chst)  
                      where x.EndsWith(chen)  
                      select x;  

        Console.Write("\n\n");
        foreach(var city in _result)  // Looping through the filtered cities and displaying them
        {  
            Console.Write("The city starting with {0} and ending with {1} is : {2} \n", chst, chen, city);  
        }  

        Console.ReadLine(); // Allowing the user to view the output before closing the console
    }  
}

Sample Output:

LINQ : Find the string which starts and ends with a specific character :                                      
-----------------------------------------------------------------------                                       
The cities are : 'ROME','LONDON','NAIROBI','CALIFORNIA','ZURICH','NEW DELHI','AMSTERDAM','ABU DHABI','PARIS'  
                                                                                                     
Input starting character for the string : N                                                                   
Input ending character for the string : I                                                                     

The city starting with N and ending with I is : NAIROBI                                                       
The city starting with N and ending with I is : NEW DELHI
