Question

I have a web service that’s pretty simple; something like this:

public class LeadService : System.Web.Services.WebService {

    [WebMethod(EnableSession = true)]
    public string MyService(string TheIncomingData)
    {
             string ReturnData = "";

             MyClass TheClass = new MyClass();
             ReturnData = TheClass.MyMethod(TheIncomingData);

             return ReturnData;
        }
}

You might have guessed it, the MyMethod is a pretty long-running method with some room for errors (for now). If I add a try/catch statement around the method call like this:

try { ReturnData = TheClass.MyMethod(TheIncomingData); }
catch { ReturnData = ""; }

Is this going to make the service and the app exception-proof? And, is using a try statement like this going to have any performance impact even if no error occurs?

Thanks for your advice.

Answer 1

Is using a try statement like this going to have any performance impact even if no error occurs?

No.

Is the application exception-proof?

Yes. However if you have onApplicationError event in the Global.asax you won’t be able to see the error since you are not throwing a new one.

But the way I see it for now, your code is safe from exceptions.
