} private void A() { try { throw new ArgumentException 试试上面的代码,可以看到其实在进入 try 时,抛出 ArgumentException 不会立刻返回到 F1 方法里面,而是会继续执行 finally 方法 在 finally 抛出的 FileNotFoundException 将会替换掉 ArgumentException 抛给了 F1 方法里面 所以答案就是在 F1 的 catch 方法,只会被触发一次,这一次的 e 就是在 finally 抛出的 FileNotFoundException

ExceptionDispatchInfo 机制 实现方法非常简单,通过 ExceptionDispatchInfo.SetRemoteStackTrace 方法即可修改异常堆栈,如以下示例 var exception = new ArgumentException {nameof(Foo.F1)} Main"); Console.WriteLine(exception); 此时控制台输出内容大概如下 System.ArgumentException: Value stack trace from previous location --- 如果想要对外抛出此加工后的异常,直接使用 throw exception; 扔掉即可,异常打印信息大概如下 System.ArgumentException ExceptionDispatchInfo.Throw 扔也可以,代码示例如下 ExceptionDispatchInfo.Throw(exception); 异常打印信息大概如下 System.ArgumentException
