The Internal Representation of Anonymous Types

All anonymous types are automatically derived from System.Object, and therefore support each of

the members provided by this base class. Given this, we could invoke ToString(), GetHashCode(),

Equals(), or GetType() on the implicitly typed myCar object. Assume our Program class defines the

following static helper function:

static void ReflectOverAnonymousType(object obj)

{

Console.WriteLine("obj is an instance of: {0}", obj.GetType().Name);

Console.WriteLine("Base class of {0} is {1}",

obj.GetType().Name,

obj.GetType().BaseType);

Console.WriteLine("obj.ToString() = {0}", obj.ToString());

Console.WriteLine("obj.GetHashCode() = {0}", obj.GetHashCode());

Console.WriteLine();

}

Now assume we invoke this method from Main(), passing in the myCar object as the parameter:

static void Main(string[] args)

{

Console.WriteLine("***** Fun with Anonymous types *****\n");

// Make an anonymous type representing a car.

var myCar = new {Color = "Bright Pink", Make = "Saab", CurrentSpeed = 55};
