Collection Initializer

Collection initializers were introduced with C# 3.0.  They provide a simpler way to add objects to collections:

Example without the collection initializer:

List<animal> animals = new List<animal>();

animals.Add( new animal { Color = “Brown”, Age = 2 } );

animals.Add( new animal { Color = “Black”, Age = 1 } );

And now with the collection initializer:

List<animal> animals = new List<animal> {

new animal { Color = “Brown”, Age = 2 },

new animal { Color = “Black”, Age = 1 }

}
