I am trying to convert an object of a class which is derived from
collectionbase class.It's not working:
while ((line = file.ReadLine()) != null && line.IndexOf(" ")!=-1)
{
al.Add(line);


}
string[] exc_string = (string[])al.ToArray(typeof(string));

somebody know why?
Thank you!
 
Without a repro case and information about what it is that goes wrong
exactly it is hard to tell.

ArrayList al = new ArrayList();
while ((line = file.ReadLine()) != null && line.IndexOf(" ")!=-1)
{
al.Add(line);


}
string[] exc_string = (string[])al.ToArray(typeof(string));

That's my program.Could u tell me why convertion faild?
Thanks!
 
ArrayList al = new ArrayList();
while ((line = file.ReadLine()) != null && line.IndexOf(" ")!=-1)
{
al.Add(line);


}
string[] exc_string = (string[])al.ToArray(typeof(string));

That's my program.Could u tell me why convertion faild?
Thanks!
 
"It's not working" is not a sufficient statement of the problem. What is
the exact error you're getting?

Not without some more information I'm afraid. Could you

1. Describe what kind of failure you see. Do you get an exception? Get
corrupted data?

2. Could you post a short but complete program (as Jon likes to put it).

No, that's not your program. It's a small part of your program.Further,
as Joakim said, you haven't provided any sample data.

Please read http://www.pobox.com/~skeet/csharp/complete.html
 
There isnt anything wrong with the code, Break on the line at the end of the
code snippet and check the contents of the ArrayList.
