Answer
Exception handling involves stack unwinding, handler search, first/second chance exceptions, managed/unmanaged boundary transitions, and finally/fault execution. Throwing is expensive due to metadata lookup and stack analysis.
Quick Answer
When an exception is thrown, the CLR searches the call stack for a matching catch handler (walking up frame by frame). Finally blocks always run during unwinding. Unhandled exceptions terminate the process. First-chance exceptions are raised before any handler — useful for debuggers. The exception object captures the stack trace at throw time.
