base keyword in C#

Base keyword in C#:

In C#, the base keyword is used to access members of the base class from within a derived class. 

  • Accessing Base Class Members: Allows access to methods, properties, and fields of the base class that are not overridden in the derived class.

  • Calling Base Class Constructors: Used to call the base class constructor from within the derived class constructor. This ensures that the base class is properly initialized.

  • Overriding and Hiding Members: When a member in the derived class overrides or hides a member in the base class, base can be used to access the overridden or hidden member.



Accessing Base Class Members:


public class BaseClass
{
    public void Display()
    {
        Console.WriteLine("BaseClass Display");
    }
}

public class DerivedClass : BaseClass
{
    public void Show()
    {
        base.Display(); // Calls Display() of BaseClass
    }
}


Calling Base Class Constructors:

public class BaseClass
{
    public BaseClass(string message)
    {
        Console.WriteLine(message);
    }
}

public class DerivedClass : BaseClass
{
    public DerivedClass() : base("Hello from BaseClass")
    {
        // Additional initialization for DerivedClass
    }
}


Overriding and Hiding Members:

public class BaseClass
{
    public virtual void Display()
    {
        Console.WriteLine("BaseClass Display");
    }
}

public class DerivedClass : BaseClass
{
    public override void Display()
    {
        base.Display(); // Calls the Display() of BaseClass
        Console.WriteLine("DerivedClass Display");
    }
}

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...
