what can cause System.IO.IOException besides for HD errors?

[Zytan]

I got a System.IO.IOException in my app on another computer, so I
couldn't debug it. I don't think it was a HD error. What else could
throw this? Could it be from reading a webpage from the internet
through a stream?

Well, what was the message from the IO exception?

From the documentation:

IOException is the base class for exceptions thrown while accessing
information using streams, files and directories.

The Base Class Library includes the following types, each of which is a
derived class of IOException :

a.. DirectoryNotFoundException

b.. EndOfStreamException

c.. FileNotFoundException

d.. FileLoadException

e.. PathTooLongException

Where appropriate, use these types instead of IOException.

So in your case, reading from a network stream could definitely do it.
Like Jon said, what's the message that is in the IOException instance?

I hate to be a wise guy here but if any .NET-app could throw a
System.IO.IOException. It would be meaningless in most cases and
probably not the answer you are looking for, but still...

Example:

using System;
class Program
{
static void Main(string[] args)
{
throw new System.IO.IOException("foo");
}
}

Wouldn't I love to know! The windows error report window doesn't show
it.

Yes, that's exactly what I was thinking. I don't know the message, I
wish I knew it! The Windows error report doesn't show it.

I put in an exception handler for my http accessing via stream, since
I believe that's where it came from, so I'll know next time.

Thanks,

System.IO.IOException.

Yes, that's true. But, I don't so this myself, and I don't use 3rd
party code, so some .NET library function threw this. I was just
wondering what type of functions that may be. I've got my answer,
now.

Most of my HD accessing is handled, and I just added exception
handling to the rest. So, that may have been my problem, maybe it was
a file being written. I assumed it wasn't since the HD has tons of
free space.
