Introduction

In this lesson, you will learn CRUD operations in .NET for beginners. CRUD stands for Create, Read, Update, and Delete. These are the basic operations used in every application.

What is CRUD?

CRUD represents four basic database operations:

• Create → Add new data
• Read → Retrieve data
• Update → Modify existing data
• Delete → Remove data

CRUD Operations using Entity Framework

Create (Insert Data)

var student = new Student { Name = "Rahul", Age = 22 };
context.Students.Add(student);
context.SaveChanges();

Read (Get Data)

var students = context.Students.ToList();

Update (Modify Data)

var student = context.Students.Find(1);
student.Name = "Amit";
context.SaveChanges();

Delete (Remove Data)

var student = context.Students.Find(1);
context.Students.Remove(student);
context.SaveChanges();
