ExpandoObject

An object you can dynamically add members to.  Lack of practical examples aside, there is a lot of possibilities because you can nest ExpandoObjects to create structured data (think XML-like/HTML-like).  You can think of ExpandoObjects as a Dictionary on steroids.  ExpandoObject is apart of the much bigger support for the Dynamic type introduced in C# 4.

   1:  public void ExpandoObject()

   2:          {

   3:              dynamic sampleObject = new System.Dynamic.ExpandoObject();

   4:              sampleObject.Test = "TestDynamic";

   5:              sampleObject.InvokeExpandoObject = new Action(() => Console.Write(sampleObject.Test));

   6:              sampleObject.InvokeExpandoObject.Invoke();

   7:          }
