parsing - Capturing groups and money symbol in Regex -


I am trying to write a regular expression that takes the string and parses it into three separate capturing groups : $ 3.99 APP Download ???? 200 11/19 a ???? 1/21 3.99 Group 1: $ 3.99 Download APP 200 Groups 2: 11/2 9 A ???? 1/28 Group 3: 3. 99

Do anyone have any ideas ???

I do not have much experience with capturing groups and I do not know how to make them.

I believe that this expression will work to identify dates? 

  / (\ d {2} \ / \ d {2}) /   
 Any help would be appreciated!   
 
 
:  
  ([$] \ d + [.] \ D {2}. * (\ D?) \ * S {1,2} / \ d {2}. *? \ D {1,2} / \ d {2}) \ s (\ d + [ .] \ D {2})   
 So with it we have 3 capture groups ( () ) different from  \ s *  , Which means 0 + white space of the alphabet (this is not necessary, but it will remove the back space from your occupied groups).  
 The first capture group  [$] \ d + [.] \ D {2}. *?  matches a dollar sign, after 1 + digit, after a period, after 2 digits, after a lazy match of 0+ characters (. *? ) In our expression (in this case, our next capture group) matches anything of this lazy match till  next  match.  
 Our second capture group is  \ d {1,2} / \ d {2}. *? \ D {1,2} / \ d {2}  matches 1-2 digits, a slash, and 2 points, then we use any lacrimal match of any other character.  
 Our final capture group will be  \ d + [.] \ D {2}  1 + digit, one duration, and 2 more digits.  
  Note:  I used  ~  as a delimiter so that we do not need to get rid of our  /  dates In addition to this, I have  $  and .  I put in character classes, because I think it looks cleaner than avoiding them ( [$]  versus  \ $ ) .. either Works :)

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
