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

1. C# Properties can be read-only or write-only.
2. We can have logic while setting values in the C# Properties.
3. 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

1. using System;  
2.    public class Employee  
3.     {  
4.         private string name;  
5.   
6.         public string Name  
7.         {  
8.             get  
9.             {  
10.                 return name;  
11.             }  
12.             set  
13.             {  
14.                 name = value;  
15.             }  
16.         }  
17.    }  
18.    class TestEmployee{  
19.        public static void Main(string[] args)  
20.         {  
21.             Employee e1 = new Employee();  
22.             e1.Name = "Sonoo Jaiswal";  
23.             Console.WriteLine("Employee Name: " + e1.Name);  
24.   
25.         }  
26.     }  

Output:

Employee Name: Sonoo Jaiswal

C# Properties Example 2: having logic while setting value

1. using System;  
2.    public class Employee  
3.     {  
4.         private string name;  
5.   
6.         public string Name  
7.         {  
8.             get  
9.             {  
10.                 return name;  
11.             }  
12.             set  
13.             {  
14.                 name = value+" JavaTpoint";  
15.                   
16.             }  
17.         }  
18.    }  
19.    class TestEmployee{  
20.        public static void Main(string[] args)  
21.         {  
22.             Employee e1 = new Employee();  
23.             e1.Name = "Sonoo";  
24.             Console.WriteLine("Employee Name: " + e1.Name);  
25.         }  
26.     }  

Output:

Employee Name: Sonoo JavaTpoint

C# Properties Example 3: read-only property

1. using System;  
2.    public class Employee  
3.     {  
4.         private static int counter;  
5.   
6.         public Employee()  
7.         {  
8.             counter++;  
9.         }  
10.         public static int Counter  
11.         {  
12.             get  
13.             {  
14.                 return counter;  
15.             }  
16.          }  
17.    }  
18.    class TestEmployee{  
19.        public static void Main(string[] args)  
20.         {  
21.             Employee e1 = new Employee();  
22.             Employee e2 = new Employee();  
23.             Employee e3 = new Employee();  
24.             //e1.Counter = 10;//Compile Time Error: Can't set value  
25.   
26.             Console.WriteLine("No. of Employees: " + Employee.Counter);  
27.         }  
28.     }  

Output:

No. of Employees: 3
