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 c# error handling get line number 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. // Only catch exceptions that you know how to handle. // Never catch base class System.Exception without // rethrowing it at the end of the catch block. } C# Copy try { // Code to try goes here. } finally { // Code to execute after the try block goes here. } C# Copy try { // Code to try goes here. } catch (SomeSpecificException ex) { // Code to handle the exception goes here. } finally { // Code to execute after the try (and possibly catch) blocks // goes here. } A try block without a catch or finally block causes a compiler error.Catch BlocksA catch block can specify the type of exception to catch. The type specification is called an exception filter. The exception type should be derived from Exception. In general, do not specify Exception as the exception filter unless either you know how to handle all exceptions that might be thrown in the try block, or you have included a throw stat

I had the idea of creating a class that is devoted to receiving and handling exceptions, but I am wondering if its a good design idea. Such a class would receive an exception and then decide what to do with it depending on its type or error code, could even parse the stack trace for specific information, etc. Here is the basic c# error handling idea behind and implementation: public class ExceptionHandler { public static void Handle(Exception e) { if (e.GetBaseException().GetType() == typeof(ArgumentException)) { Console.WriteLine("You caught an ArgumentException."); } else { Console.WriteLine("You did not catch an exception."); throw e; // re-throwing is the default behavior } } } public static class ExceptionThrower { public static void TriggerException(bool isTrigger) { if (isTrigger) throw new ArgumentException("You threw an exception."); else Console.WriteLine("You did not throw an exception."); } } class Program { static void Main(string[] args) { try { ExceptionThrower.TriggerException(true); } catch(Exception e) { ExceptionHandler.Handle(e); } Console.ReadLine(); } } I thought this would be an interesting endeavor because you would theoretically only need one or very few try / catch blocks around your main() method calls, and let the exception class handle everything else including re-throwing, handling, logging, whatever.
