[antlr-interest] Verbatim string literal in C#

[X f]

Hi, All:
  How can I express a lexer rule to parse verbatime
  literal string in C#? This literal starts by '@"'
  and stop by '"'. It can not have a single " in
between, but can have double quote ("") as quote
escape. 

   I used:
VERBATIM_LITERAL 
  : '@' '"' ( (~'"' ~'"') | '"' '"'  )* '"'	
  ;

   It seems it can only work on @"""", If I put 
  @" aaa ", it will treat the last " as illegal
character

Cheers
