String Palindrome in C#

String Palindrome in C#

Write a program to check if a given string is a palindrome in c# .

using System;

public class Program

{

    public static void Main()

    {        

        string Orginal = "ISI";

        char[] arr = Orginal.ToCharArray();

        Array.Reverse(arr);


        bool isPalindrome = (Orginal == new string(arr));

        string results = isPalindrome ? "Palindrome" : "Not Palindrome";


        Console.WriteLine(Orginal + " is " + results);

    }

}


Output:

ISI is Palindrome



Using LINQ:

Write a program to check if a given string is a palindrome using LINQ.

string.Join combines the reversed characters into a string.

StringComparison.OrdinalIgnoreCase makes the comparison case-insensitive.


This reverses the characters of the string str and creates a new string (reversed).

string reversed = string.Join("", str.Reverse());


This compares the original string str with the reversed string reversed, ignoring case differences, to check if they are the same (i.e., if the string is a palindrome).

if (str.Equals(reversed, StringComparison.OrdinalIgnoreCase))


using System;

using System.Linq;


public class Program

{

    public static void Main()

    {        

        Console.Write("Enter a string: ");

        string str = Console.ReadLine();

        string reversed = string.Join("", str.Reverse());


        if (str.Equals(reversed, StringComparison.OrdinalIgnoreCase))

        {

            Console.WriteLine("The string is a palindrome.");

        }

        else

        {

            Console.WriteLine("The string is not a palindrome.");

        }

    }

}




Output:

Enter a string: ISI
The string is a palindrome.

EF Core interview questions for beginners

1. What is Entity Framework Core (EF Core)? EF Core is an open-source Object-Relational Mapper (ORM) that enables .NET developers to work with databases using .NET objects. It allows you to interact with a database using strongly typed classes and LINQ queries, rather than writing raw SQL queries. EF Core supports various database providers, such as SQL Server, SQLite, PostgreSQL, MySQL, and more. 2. What are the advantages of using EF Core over traditional ADO.NET? Productivity:  EF Core allows you to work with databases using high-level objects, reducing the amount of boilerplate code you need to write. Cross-platform:  EF Core supports multiple databases and works on Windows, Linux, and macOS. LINQ Support:  You can query the database using LINQ, which is more type-safe and easier to maintain than raw SQL queries. Code-First & Database-First:  EF Core supports both approaches to model databases. Change Tra...

EF Core interview questions for experienced

EF Core interview questions for experienced 1. What are the main differences between Entity Framework (EF) and Entity Framework Core (EF Core)? EF Core is a complete rewrite of EF. Unlike EF, EF Core supports cross-platform development, improved performance, LINQ query translation, and has a more modular architecture. EF Core does not support all features that EF 6 does (like lazy loading and some database providers). 2. How does EF Core handle migrations, and what are some common pitfalls? EF Core uses migrations to update the database schema based on model changes. Common pitfalls include not applying migrations correctly, misalignment between model and database state, or missing/overwriting migrations during collaboration in a team environment. 3. Explain the difference between Add and Attach methods in EF Core. Add method is used to add a new entity to the context and mark it as Added , while Attach attaches an existing entity to the context with no changes. The Attach meth...
