Will a using clause close this stream?

Question

I\'ve apparently worked myself into a bad coding habit. Here is an example of the code I\'ve been writing:

using(StreamReader sr = new StreamReader(File.Open         


        

Answer 1

Since this doesn't seem to be a coding issue, I'm going to put my syadmin hat on and offer a few suggestions.

1. Virus scanner on either the client or server that's scanning the file as it's created.
2. Windows opportunistic locking has a habit of screwing things up on network shares. I recall it being mostly an issue with multiple read/write clients with flat file databases, but caching could certainly explain your problem.
3. Windows file open cache. I'm not sure if this is still a problem in Win2K or not, but FileMon would tell you.

Edit: If you can catch it in the act from the server machine, then Sysinternal's Handle will tell you what has it open.
