Write Only Properties

When the value of a property can only be changed outside the class it is called a write-only property.
This is rarely seen or used.
There may also be times when you want the client to change a value but not to retrieve it.
This rarely makes sense though

Removing Get

To create a read-only field you can exclude the get altogether.

public class Animal 
{ 
   private int _Age; 

   public int Age 
   {   
      set { this._Age = value; } 
   } 
} 

Private Get

Alternatively if you still needed to set the value inside the class then you can change it to private.

public class Animal 
{ 
   private int _Age; 

   public int Age 
   { 
      private get { return this._Age; } 
      set { this._Age = value; } 
   } 
}
