This attribute is used on a method to
indicate that it can accept a variable
number of parameters. The method has an array as its last parameter,
and the list of values passed to the method are stored in the array.
In C#, use the params keyword to create methods
with a variable number of arguments, rather than using this attribute
directly.
public sealed class ParamArrayAttribute : Attribute {
// Public Constructors
public ParamArrayAttribute( );
