Exceptions and 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  The C# language's exception handling features help you deal with any unexpected or exceptional situations that occur when a program is running. Exception handling uses the try, catch, and finally keywords to try actions that may not succeed, to handle failures when you decide that it is reasonable to do so, and to clean up resources afterward. Exceptions can be generated by the common language runtime (CLR), by the .NET Framework or any third-party libraries, or by application code. Exceptions are created by using the throw keyword.In many cases, an exception may be thrown not by a method that your code has called directly, but by another method further down in the call stack. When this happens, the CLR

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 http://stackoverflow.com/questions/5573814/an-exception-handling-class even parse the stack trace for specific information, etc. Here is the basic 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.

Our objectives are as follows: Learn what an exception is Implement a routine with a try/catch block Release resources in a finally block Exceptions Exceptions are unforeseen errors that happen in your programs. Most of the time, you can, and should, detect and handle program errors in your code. For example, validating user input, checking for null objects, and verifying the values returned from methods are what you expect, are all examples of good standard error handling that you should be doing all the time. However, there are times when you don't know if an error will occur. For example, you can't predict when you'll receive a file I/O error, run out of system memory, or encounter a database error. These things are generally unlikely, but they could still happen and you want to be able to deal with them when they do occur. This is where exception handling comes in. When exceptions occur, they are said to be "thrown". What is actually thrown is an object that is derived from the System.Exception class. In the next section, I'll be explaining how thrown except
