Use Object Initializers with Properties

As discussed in Chapter 8, C# 3.0 adds a new feature called an 

object initializer

, which 

provides an alternative to explicitly calling a constructor when creating an object. When 

using object initializers, you specify initial values for the fields and/or properties that you 

want to initialize. Furthermore, the object initializer syntax is the same for both properties 

or fields. For example, here is the object initializer demonstration program from Chapter 8, 

reworked to show the use of object initializers with properties. Recall that the version 

shown in Chapter 8 used fields. The only difference between this version of the program 

and the one shown in Chapter 8 is that 

Count

 and 

Str

 have been converted from fields into 

properties. The object initializer syntax is unchanged.

// Use object initializers with properties.

using System;

class MyClass {

  // These are now properties.

  public int Count { get; set; }

  public string Str { get; set; }

}

class ObjInitDemo {

  static void Main() {

    // Construct a MyClass object by using object initializers.

    MyClass obj = new MyClass { Count = 100, Str = "Testing" };

    Console.WriteLine(obj.Count + " " + obj.Str);

  }

}
