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.

This article describes best practices for handling and creating exceptions.Handling exceptionsThe following list contains some general guidelines for handling exceptions in your app.Use exception handling code (try/catch blocks) appropriately. You can also programmatically check for a condition that is likely to occur without using exception handling. Programmatic checks. The following example uses an if statement to check whether a connection is closed. If it isn't, the example closes the connection instead of throwing an exception. C#C++VB Copy if (conn.State != ConnectionState.Closed) { conn.Close(); } Exception handling. The following example uses a try/catch block to check the connection and to throw an exception if the connection is not closed. C#C++VB Copy try { conn.Close(); } catch (InvalidOperationException ex) { Console.WriteLine(ex.GetType().FullName); Console.WriteLine(ex.Message); } The method you choose depends on how often you expect the event to occur.

A C# exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero. Exceptions provide a way to transfer control from one part of a program to another. C# exception handling is built upon four keywords: try, catch, finally, and throw. try: A try block identifies a block of code for which particular exceptions is activated. It is followed by one or more catch blocks. catch: A program catches an exception with an exception handler at the place in a program where you want to handle the problem. The catch keyword indicates the catching of an exception. finally: The finally block is used to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be clo

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 NullRefere
