What are Classes and Objects in C# .NET?<\/h2>\n

In C#, classes<\/strong> and objects<\/strong> are fundamental building blocks of object-oriented programming. A class serves as a blueprint, while objects are instances created from this blueprint when your program runs. Let\u2019s explore these concepts in detail.<\/p>\n

Classes in C#<\/h3>\n

A class<\/strong> is a block of code that performs a specific task. It defines the properties, methods, and behaviors that an object created from the class will have. Classes can be reused across different parts of your application or even in other projects, saving time and effort in rewriting code.<\/p>\n

Think of a class as a recipe<\/strong> for creating something. For example, if you have a recipe for chicken biryani, the recipe itself provides instructions for how to make the dish. However, the recipe is not the biryani itself; it\u2019s just the instructions. Whenever you want to cook biryani, you follow the recipe. Similarly, a class provides the instructions (code) to create an object, but it\u2019s not the object itself.<\/p>\n

Example of a Class:<\/h4>\n
\r\npublic class Car {\r\n    public string Make { get; set; }\r\n    public string Model { get; set; }\r\n    \r\n    public void StartEngine() {\r\n        Console.WriteLine(\"The engine has started.\");\r\n    }\r\n}\r\n<\/code><\/pre>\n
In this example, Car<\/code> is a class that defines two properties, Make<\/code> and Model<\/code>, and one method, StartEngine()<\/code>.<\/p>\n
Objects in C#<\/h3>\n
An object<\/strong> is an instance of a class. It\u2019s the real thing that is created from the class. Using the biryani analogy, an object is the actual chicken biryani<\/strong> you create using the recipe (class). You define the class once and then use it to create multiple objects (biryani dishes) whenever needed.<\/p>\n
An object is how you use a class in practice. It contains the actual data and methods defined in the class, and you interact with these through the object. In C#, you create objects using the new<\/code> keyword.<\/p>\n
Example of an Object:<\/h4>\n
\r\npublic class Program {\r\n    public static void Main() {\r\n        \/\/ Creating an object of the Car class\r\n        Car myCar = new Car();\r\n        myCar.Make = \"Toyota\";\r\n        myCar.Model = \"Camry\";\r\n        \r\n        \/\/ Calling the method of the Car class\r\n        myCar.StartEngine();\r\n    }\r\n}\r\n<\/code><\/pre>\n
In this example, myCar<\/code> is an object created from the Car<\/code> class. We assign values to its properties and call its method. The object myCar<\/code> is an instance of the Car<\/code> class, representing a specific car.<\/p>\n
