C# Automatic Properties

Question

I\'m a bit confused on the point of Automatic properties in C# e.g

public string Forename{ get; set; }

I get that you are saving code by no

Answer 1

Take a look at the following code and explanation.
The most common implementation for a property is getter or a setter that simply reads and writes to a private field of the same type as a property. An automatic property declaration instructs the compiler to provide this implementation. The compiler automatically generates a private backing field.
Look into the following code:-

    public class Stock 
    {
      decimal currentPrice ;  // private backing field.
      public decimal CurrentPrice 
      {
        get { return currentPrice ; }
        set { currentPrice = value ; }
      }
   }

The same code can be rewritten as :-

   public class Stock
   {
     public decimal CurrentPrice { get ; set ; } // The compiler will auto generate a backing field.
   }
