The first to match will be executed, so remember to place the most generic type at the end and the most specialized at the start For example, if you were to place the catch clause for Exception ahead of the clause for XmlException and ConfException, neither of these would ever be invoked This is because both of these classes belong to the Exception type, and would therefore match the first clause The first catch clause (FileException) is invoked if there is a problem with the configuration file (if the file is non-existent or unwriteable) The second clause (XmlException) is invoked if an error occurs in parsing the XML file (if an element is not closed, for example) The third clause (ConfException) is invoked if a valid XML file does not contain the expected root conf element. pdf report in c#: Free .NET PDF Component - Developing PDF in C# , VB.NET, ASP ... c# pdf parse table Save PDF file to Stream and Load PDF file from Stream in C#

The final clause (Exception) should not be reached, because our methods only generate the three exceptions, which are explicitly handled It is often a good idea to have a backstop clause like this, in case you add new exceptions to the code during development The benefit of these fine-grained catch clauses is that they allow you to apply different recovery or failure mechanisms to different errors For example, you may decide to end execution, log the error and continue, or explicitly rethrow an error: try { //.. } catch ( FileException $e ) { throw $e; }.

Have you looked at this project, which is also on CodeProject? It's C# and uses/wraps an open source C/C++ PDF library. The code and compiled binary can be ... Another trick you can play here is to throw a new exception that wraps the current one. This allows you to stake a claim to the error, to add your own contextual information, while retaining the data encapsulated by the exception you have caught. You can read more about this technique in 15. So what happens if an exception is not caught by client code It is implicitly rethrown, and the client s own calling code is given the opportunity to catch it. This process continues either until the exception is caught or until it can no longer be thrown. At this point, a fatal error occurs. Here s what would happen if we did not catch one of the exceptions in our example: PHP Fatal error: Uncaught exception 'FileException' with message 'file 'nonexistent/not_there.xml' does not exist' in ... So when you throw an exception, you force the client to take responsibility for handling it. This is not an abdication of responsibility. An exception should be thrown when a method has detected an error but does not have the contextual information to be able to handle it intelligently. The write() method in our example knows when the attempt to write will fail, and it knows why, but it does not know what to do about it. This is as it should be. If we were to make the Conf class more knowledgeable than it currently is, it would lose focus and become less reusable.
