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 c# error handling get line number 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. // 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 compile

Best Practices for Exceptions .NET Framework (current version) Other Versions Visual Studio 2010 .NET Framework 4 Silverlight .NET Framework 3.5 .NET Framework 3.0 .NET Framework 2.0 .NET Framework 1.1 A well-designed app handles exceptions and errors to prevent app crashes. This article describes best practices for handling and creating exceptions.Handling exceptionsThe https://msdn.microsoft.com/en-us/library/seyhszts(v=vs.110).aspx 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. Use exception handling if the event doesn't occur very often, that is, if the event is truly exceptional and indicates an error (such as an unexpected end-of-file). When you use exception handling, less code is executed in normal conditions.Use the programmatic method to check for errors if the event happens routinely and could be considered part of normal execution. When you check for errors programmatically, more code is executed if an exception occurs

RemarksWhen c# error handling an exception is thrown, the common language runtime (CLR) looks for the catch statement that handles this exception. If the currently executing method does not contain such a catch block, the CLR looks at the method that called the current method, and so on up the call stack. If no catch block is found, then the CLR displays an unhandled exception message to the user and stops execution of the program.The try block contains the guarded code that may cause the exception. The block is executed until an exception is thrown or it is completed successfully. For example, the following attempt to cast a null object raises the NullReferenceException exception: C# Copy object o2 = null; try { int i2 = (int)o2; // Error } Although the catch clause can be used without arguments to catch any type of exception, this usage is not recommended. In general, you should only catch those exceptions that you know how to recover from. Therefore, you should always specify an object argument derived from System.Exception For example: C# Copy catch (Inv
