C sharp - Parameterized Constructor

What is a Parameterized Constructor?

A parameterized constructor is a constructor that takes arguments (parameters). It allows you to initialize object properties with specific values at the time of object creation.

Why Use It?

• To set initial values for object fields.

• To avoid using separate setter methods after creating the object.

Syntax

class ClassName
{
    public ClassName(type parameter1, type parameter2)
    {
        // Use parameters to initialize fields
    }
}

Simple Example

using System;

class Student
{
    public string name;
    public int age;

    // Parameterized constructor
    public Student(string studentName, int studentAge)
    {
        name = studentName;
        age = studentAge;
    }

    public void DisplayInfo()
    {
        Console.WriteLine("Name: " + name);
        Console.WriteLine("Age: " + age);
    }
}

class Program
{
    static void Main()
    {
        // Create object with specific values
        Student s1 = new Student("Alice", 20);
        s1.DisplayInfo();
    }
}
