Modifying the underlying collection in the body of the Action(T) delegate is not supported and causes undefined behavior.
The following example demonstrates the use of the Action(T) delegate to print the contents of a List(T) object. In this example the Print method is used to display the contents of the list to the console.
In addition to displaying the contents using the Print method, the C# example demonstrates the use of anonymous methods to display the results to the console.
