c# - Catching exceptions with catch, when - Stack Overflow When an exception is thrown, the first pass of exception handling identifies where the exception will get caught before unwinding the stack; if when the "catch" location is identified, all "finally" blocks are run (note that if an exception escapes a "finally" block, processing of the earlier exception may be abandoned)
Difference between try-finally and try-catch - Stack Overflow Within the catch block you can respond to the thrown exception This block is executed only if there is an unhandled exception and the type matches the one or is subclass of the one specified in the catch block's parameter Finally will be always executed after try and catch blocks whether there is an exception raised or not
