C# Properties
C# Properties
C# Properites doesn't have storage location. C# Properites are extension of fields and accessed like fields.
The Properties have accessors that are used to set, get or compute their values.
Usage of C# Properties
- C# Properties can be read-only or write-only.
- We can have logic while setting values in the C# Properties.
- We make fields of the class private, so that fields can't be accessed from outside the class directly. Now we are forced to use C# properties for setting or getting values.
C# Properties Example
using System;
public class Employee
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name = value;
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
e1.Name = "Sonoo Jaiswal";
Console.WriteLine("Employee Name: " + e1.Name);
}
}
Output:
Employee Name: NAvneet Rana
C# Properties Example 2: having logic while setting value
using System;
public class Employee
{
private string name;
public string Name
{
get
{
return name;
}
set
{
name = value+" Lakneswar";
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
e1.Name = "Navneet";
Console.WriteLine("Employee Name: " + e1.Name);
}
}
Output:
Employee Name: Navneet Lakneswar
C# Properties Example 3: read-only property
using System;
public class Employee
{
private static int counter;
public Employee()
{
counter++;
}
public static int Counter
{
get
{
return counter;
}
}
}
class TestEmployee{
public static void Main(string[] args)
{
Employee e1 = new Employee();
Employee e2 = new Employee();
Employee e3 = new Employee();
//e1.Counter = 10;//Compile Time Error: Can't set value
Console.WriteLine("No. of Employees: " + Employee.Counter);
}
}
Output:
No. of Employees: 3
