Question Need code(s)s to Catch specific IOException(s)

[motoburn]

Does anyone know a link to a list of IOException codes or some way of catching a specific error?

I have been digging for a couple hours trying to find a code, or a number to catch when my app throws

System.IO.IOException was unhandled
  Message="The file exists. "
  Source="mscorlib"

For this app, I am simply moving all files in specified directory to a directory on the file server. It is likely that a file being moved will already exist, in which case, I need to move the file to a different directory so it can be analyzed...

I am sure I could run

 If File.Exists(...)=False Then
File.Move(...)
Else
File.move(..., somewhereElse)
end if

but I thought it would be cleaner in a Try/Catch block.

Should I just use the If/Then? I have used the MySqlException which has a number assigned to each exception, so I can catch duplicate keys and insert them into a temp table for analysis.... was hoping to do something similar here, but I can't seem to find any reference to System.IO.IOException's..
I'm sure this is a simple noob question, but, there it is. Thanks for any help in advance

Use both:

Try
  If Not File.Exists(...) Then
        File.Move(...) 'Could still error here
  Else
        Files.Move(elsewhere...) 'Could still error
  End If
Catch IOex As IOException
    'Code here
Catch ex As Exception
    'Generic code here
End Try

That looks nice, thankyou. I didnt think of using both the try/catch and the if/then.

Thanks again,
