c# - Double.Parse("string") FormatException with correct input -

-

I'm trying to parse 

  double. Purse (row data [j ++]).   
 The input sting is correct ("7,412"), j = 123 so it worked till this point.  
 And even if I'm typing  double. (Row data [j])  This works.  
 Is there a problem here?  
 
 
 
 You have a comma rather than your decimal separator  
 
  
 You should use  allowHouse   number type  if it is thousands separator  
  number style style = number style . Allow thousands. NumberStyles.Float; Double. Purse (value, style);   
 Or you  your comma. Before parsing using  string.Replace  with  it is considered as a decimal separator
