Docs: Remove or replace catch blocks that handle Exception

Created on 4 Apr 2018  路  6Comments  路  Source: dotnet/docs

There are a lot of examples demonstrating the use of "catch(Exception)" or "catch{}" that leads application to unexpected behavior.
Literally such catch block says "whatever happened lets do one thing". In most cases it does not make sense.

For example, on this page there is code catch (Exception ex) { Console.WriteLine("Exception caught in CreateTestMessage1(): {0}", ex.ToString() );
In case of any issues with application itself or environment that finished by Exception (NullReferenceException, OutOfMemoryException etc) we just swallow that exception and put some information in to console. First of all any unhandled exception in console application will be written to console by itself. Second, should the caller of this method be notified about something happened? Again, in most cases yes, because mostly code that follows this method assumes this method success. If the task was just "try to send email" then we should put appropriate exception types (SmtpFailedRecipientException, SmtpException etc), because other exceptions do not mean email was not sent, situation when exception was thrown after email was sent possible too. In common other exceptions not stated in documentation can be not related to email sending at all.

Statement from c# Programming Guide:
Do not catch an exception unless you can handle it and leave the application in a known state. If you catch System.Exception, rethrow it using the throw keyword at the end of the catch block.
More information here: MSDN

I think in most cases try/catch blocks can be just removed from examples. Sometimes they can be replaced/improved by exact exception type catching and sometimes by rethrowing.
In very rare case catch{} makes sense in context of application lifetime considering.

We have fixed such several examples, but there are much more of them (example) (especially in code related to UWP).
I'd like to assign to it, but anyway I want to discuss it as new examples will be added, may be it makes sense to create documentation tests, for example.

@mairaw , asking you, please, kindly review this issue as you already had a deal with it

Thanks for opening this issue, @jinek. This is a problem throughout the documentation set, so I've added it to the .NET Community Contributors project.. So if anyone would like to work on this, please let us know.
The handling of Exception is particularly widespread in legacy code (that is, examples written for .NET Framework 1.0, 1.1, and 2.0 that have not been revised subsequently). The problems are:

  • Exception handling with Exception is used when no exception handling is needed. It evidently was part of a samples boilerplate, and so sometimes even appears when calling methods that don't throw an exception.
  • Exception handling with Exception is used instead of handling more specific exceptions. As a general rule, catching Exception rather than more derived exceptions is not recommended.
  • There are also cases of catching ApplicationException and SystemException. Neither practice is recommended. (I'll open separate issues for these.)

I would like to work on it

Thank you so much for your offer to help with addressing exception handling in the doc set, @jinek! I'll respond by tomorrow with a detailed plan for reviewing the examples that will help to get you started.

To address the issue of incorrect exception handling:

  1. Work in the dotnet/samples repo.
  2. Find the line of code that handles Exception.
  3. Determine whether exception handling is needed at all. If not, simply delete the try statement and the catch block.
  4. Identify the methods in the try block that are candidates for throwing an exception, and replace that particular catch statement with one or more catch statements that handle the appropriate exception.

The following are some of the samples that catch Exception. These are all C# examples. In most cases, there is a parallel Visual Basic example in the corresponding snippets\visualbasic directory, and there is sometimes an example in the corresponding snippets\cpp directory.
