Title: a) Design form for employee registration, make it a class, create it object and access it. OR   b) Create a console program to create a class “Employee” with fields as Name, Empl_id, email_id, Contact_no, designation, department, etc. Create its object and access it.

Theory:

Syntax and Definition of Class, object, constructor, destructor, get and set methods.

• Class: A class definition starts with the keyword class followed by class name; and the class body enclosed by pair of curly braces.

• Object : objects can be created by using the new keyword by the same name of the class that the object will be based on.
Syntax:
class_name obj = new class_name();

• Constructor: The constructor is a special type of method in c# programming language that is called or invoked automatically when an object of the given class is created. There are basic two type of constructor default and parameterized.
Syntax:
public class user
{
    // constructor public user()
    {
        // your custom code or body }
    }
}


• Destructor: Destructors are just the opposite of constructors. It is a special method of the class that is invoked when a class object goes out of scope. Similar to a constructor, a destructor name is also exactly the same as that of the class name but with a prefix of “~” (tilde).

Syntax:
class Example
{
    // Rest of the class
    // members and methods.
    // Destructor
    ~Example()
    {
        // your code or body
    }
}


• Accessors: The block of “set” and “get” is known as “Accessor”. It is very essential to restrict the accessibility of property.

• get() : It specifies that the value of a field can access publicly. It return a single value and it specifies the read-only property.

• set() : It will specify the assignment of a value to a private field in a property. It return a single value and it specifies the write-only property.

Syntax for get() and set():
<access_modifier> <return_type> <property_name>
{
    Get{ // body}
    Set{ // body}
}


Console application code:

using  System;
namespace  Console_Employee
{
class  Employee
{
int  Emp_id;
String  name;  
String Email_id;  
long contact_no;
String destination;  
String dept;
public  Employee()
{
Emp_id  =  0;
name  =  "NULL";
Email_id  =  "employeexyz@gmail.com";
contact_no  =  00000;
destination  =  "mumbai";
dept  =  "XYZ";
}
public  Employee(int a, String n, String e, long c, String de, String  dt)
{
Emp_id  =  a;
name  =  n;
Email_id  =  e;
contact_no  =  c;
destination  =  de;
dept  =  dt;
}
public  void  display()
{
Console.WriteLine(Emp_id+  "  \t  "  +name+  "  \t  "
+Email_id+  "\t"  +contact_no+  "\t"  +destination+  "\t"+dept);
}
}
class  Program
{
static  void  Main(string[]  args)
{
int  id; String  n; String  e; long  c; String  de; String  dt;

/*taking  input  or  employee  info   from  user */

Console.WriteLine("Enter  employee  id  :");
string  val  =  Console.ReadLine();
id  =  Convert.ToInt32(val);

Console.WriteLine("Enter  employee  name:");
n  =  Console.ReadLine();

Console.WriteLine("Enter  employee  Email_id:");
e  =  Console.ReadLine();

Console.WriteLine("Enter  employee  contact  NO:");
string  val2  =  Console.ReadLine();
c  =  Convert.ToInt64(val2);

Console.WriteLine("Enter  employee  destination:");
de  =  Console.ReadLine();  

Console.WriteLine("Enter employee  department:");  
dt  =  Console.ReadLine();

Employee  e1  =  new  Employee(id,n,e,c,de,dt);
e1.display();

//  By  parameterized  constructor
Employee  e2  =  
new Employee
(1,"Maroof","maroof49@gmail.com",9320789456,"jogeswari","Computer");
e2.display();

//  By  default  constructor Employee  e3  =  new  Employee();

e3.display();
Console.ReadKey();
}
}
}


Observations/ Results:

Output :

Default constructor :

OPEN IMAGE IN NEW TAB FOR BEST RESULT

Parameterized constructor :


Taking input from user :


Conclusion:

I have learned to implement classes, objects , constructor , destructor , access methods i.e get() and set()  in C Sharp(#) programming successfully.
