What is the get and set function?

Consider this simple property together with its backing field:

  private string name;

  public string Name

  {

     get { return name;  }

     set { name = value; }

  }

The property 'get' returns the value of the backing field.

The property 'set' sets the value of the backing field to 'value'.

The compiler sorts out which one you mean.

So:

  Name = "Fred"; // calls the property set with a value of 'Fred'

  string s = Name; // calls the property get which returns 'Fred' and assigns it to 's'.

Consider also these methods:

  public string get_Name()

  {

     return name;

  }

  public void set_Name(string value)

  {

     name = value;

  } 

and these method calls:

  set_Name("Fred");

  string s = get_Name();

 

The property get and set behave exactly like the methods get_Name and set_Name and in fact the compiler converts properties to such methods under the hood.
