Create a new student class with three properties: id, firstname, and lastname. override the tostring() method to display student information. create two new student objects and print their contents by calling tostring() inside a console. writeline() statement.

Following are the program in c#

using System;// namespace

public class student1  // main class

{

   public static void Main(string[] args) // main method

   {

       Student sam = new Student("45", "san", "tan");

       Student ram = new Student("104", "ran", "pan");

       Console.WriteLine(sam); // print the data of first object  

       Console.WriteLine(ram);// print the data of second object  

   }

}

public class Student // student class

{

   public string ID ;// properties id  

   public string FirstName; //properties name

   public string LastName; //properties LastName;

   public Student(string id, string firstName, string lastName) // parametrized constructor

   {

       ID = id;

       FirstName = firstName;

       LastName = lastName;

   }

public override string ToString() // overriding the method ToString

   {

return "ID: " + ID + ",  FirstName: " + FirstName + " LastName:" + LastName;

   }

}

Explanation:

In this program we create a class student and declared a three variable  i.e ID, FirstName, and LastName  .We initialize them into into constructor and create a override method  ToString() which return the string .In the main method method we create a two object  of student class and display them using writeline method .

Output:

ID:45, FirstName:san lastName:tan

ID:104, FirstName:ran lastName:pan
