Exception Handling (C# Programming Guide) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 A try block is used by C# programmers to partition code that might be affected by an exception. Associated catch blocks are used to handle any resulting exceptions. A finally block contains code that is run regardless of whether or not an exception is thrown in the try block, such as releasing resources that are allocated in the try block. A try block requires one or more associated catch blocks, or a finally block, or both.The following examples show a try-catch statement, a try-finally statement, and a try-catch-finally statement. C# Copy try { // Code to try goes here. } catch (SomeSpecificException ex) { // Code to handle the exception goes here. // Onl

Error Raising and Handling Guidelines .NET Framework 1.1 The following rules outline the guidelines for raising and handling errors: All code paths that result in an exception should provide a method to check for success without throwing an exception. For example, to avoid a FileNotFoundException you can call File.Exists. This might not always be possible, but the goal is that under normal execution no exceptions should be thrown. End Exception class names with the Exception suffix as in the following code example. VB Copy Public Class FileNotFoundException Inherits Exception ' Implementation code goes here. End Class

It makes me confused because in my thinking users should know what happens with the system. c# error handling Please give me some advice. c# .net exception exception-handling try-catch share|improve this question edited Feb 20 '13 at 6:45 user1645055 asked Feb 20 '13 at 6:32 Toan Nguyen 5,55231841 87 Snippet #1 is 99.999% of the time unacceptable. –leppie Feb 20 '13 at 6:33 14 Displaying exception directly to user is never a good idea mainly for two reasons: 1. if it's usual user (s)he will be annoyed reading error message that tells very few for him/her. 2. if (s)he's, so called, hacker (s)he may get useful information. The best practice, IMO, is to log exception and show friendly error message. –Leri Feb 20 '13 at 6:35 3 @leppie If something unexpected occurs (like NullReference or ArgumentNull that is not part of application flow) it means that there's a bug that needs to be fixed so logging them will help to debug your code much faster. –Leri Feb 20 '13 at 6:42 9 Using a try-catch block to hide an exception is generally the result of lazy programming. It's a shortcut that is often used instead of writing validation code to test inputs. Very occasionally there are times when an exception may arise that doesn't affect the operation of your code, and hiding it like this might be OK. This is fairly rare however. –Corey Feb 20 '13 at 6:43 11 @T
