It would help if you could give a bit more information. Is there any reason why you need to use an array instead of a List<string> which you can keep adding to? How are you going to populate the array? What will you do with it afterwards? Jon > > i must create an string array to save a record of a txt file.... the > > number of record is't the same...

All of operation, are in a "FOR" loop or cycle( i don't now which word is better ) can you understand? thanks > > It would help if you could give a bit more information.

No, I think you should use a List<string> (or ArrayList, or something similar) rather than an array so that you don't need to know how many items to create before you start.
