Which to catch first?

[Rasika WIJAYARATNE]

I've got a C++/CLI winforms app that calls web services. I am trying to wrap
my calls the WS in a try/catch block and need to catch the following two
exceptions:

System.Net.WebException
Thrown when no connection to internet on client computer.

System.Web.Services.Protocols.SoapException
Thrown when WS server's SqlServer is unavailable (WS returns data from the
SqlServer).

I would like to know which one I should catch first?

It makes no difference. Neither is derived from the other, so the order of
catches will have no effect on the meaning of the code.

-cd
