Try/catch blocks inside constructors

问题

Is it a bad programming practice to have try/catch blocks inside constructors? Or does it make no difference as long as our programs handle typeinitializer exceptions gracefully.

In C# if there are any exceptions inside a constructor the framework always throws typeinitilizer exceptions.

Thanks, Shamika

回答1:

System.TypeInitializationException is thrown when a static constructor throws an exception, not on an instance constructor. Exceptions are thrown normally in instance constructors.

That aside, there's nothing "wrong" with it any more than it is anywhere else; handle exceptions that you can properly recover from, and allow those that you can't to bubble up.
