[antlr-interest] How to interpret object creation sentence?

[Alexey Demakov]

If you need to create object for the given class name you can use CreateInstance method in Assembly class.
Assembly is returned by the correspondent property of System.Type class.

System.Type type = ...;
object instance = type.Assembly.CreateInstance( fullName )

But it is not so easy - you need to know fully qualified name of class to create, not just last identifier.

  Now I want to interpret an object creation with actions in C#, source syntax like "new ClassName()",  objective code is the same, such as" ClassName aObject=new ClassName();"

  The first grammar is refused by C# compiler,
  createObject returns [Object o=null]
   :
   "new" id:ID LPAREN RPAREN { o= new  id.getText()+"()";} 
   ;

  The second just return a string, e.g. "new ClassName ()",
  createObject returns [string r=null]
   :
   "new" id:ID LPAREN RPAREN{r= "new "+id.getText()+"()";}
   ;

  Could any ony give me an idea?
